What are congruent triangles?
Suppose it is given that two triangles ΔABC ≅ ΔDEF
Then that means ΔABC and ΔDEF are congruent. Congruent triangles are exact same triangles, but they might be placed at different positions.
The order in which the congruency is written matters.
For ΔABC ≅ ΔDEF, we have all of their corresponding elements like angle and sides congruent.
Thus, we get:
[tex]\rm m\angle A = m\angle D \: or \: \: \angle A \cong \angle D \angle B = \angle E\\\\\rm m\angle B = m\angle E \: or \: \: \angle B \cong \angle E \\\\\rm m\angle C = m\angle F \: or \: \: \angle C \cong \angle F \\\\\rm |AB| = |DE| \: \: or \: \: AB \cong DE\\\\\rm |AC| = |DF| \: \: or \: \: AC \cong DF\\\\\rm |BC| = |EF| \: \: or \: \: BC \cong EF[/tex]
(|AB| denotes length of line segment AB, and so on for others).
We are given that;
The diagram
Now,
Based on the information given in the diagram, we can use the following congruence theorems or postulates as reasons why ABC= ADEF:
SAS (Side-Angle-Side): If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent.
We can use SAS to show that ABC and ADEF are congruent, since AB = AD, BC = DE, and the included angle BAC = the included angle EDF.
AAS (Angle-Angle-Side): If two angles and a non-included side of one triangle are congruent to two angles and the corresponding non-included side of another triangle, then the triangles are congruent.
We can use AAS to show that ABC and ADEF are congruent, since the included angles BAC and EDF are congruent, angle ABC is congruent to angle ADE (since they are vertical angles), and side BC is congruent to side EF.
Therefore, by congruent triangles the answer will be SAS, AAS.

What does RS equal?
Work Shown:
PR*RT = QR*RS
4*15 = 5*RS
60 = 5*RS
RS = 60/5
RS = 12
For more information, check out the intersecting chords theorem. This is the idea where multiplying pieces of two chords leads to the same product. A chord is any segment where both endpoints are on the edge of the circle.
RS is equal to 12.
In a circle, two chords that intersect inside of a circle is given by this formula: PR * RT = QR * RS
Since these two chords are equal, we can set up this equation by putting what we know so far. Since PR * RT = 15 * 14 = 60, and QR * RS = 5 * RS, we get 5 * RS = 60. This is just a simple algebraic expression now.
Dividing by 5 from both sides, we get [tex]\frac{RS}{5}[/tex] = [tex]\frac{60}{5}[/tex].
We then get RS = 12. This wasn't so bad, right?

Geometry question I need help with it
Answer:
True, False, False, False
Step-by-step explanation:
I'll find the lengths of all sides of the drawing before answering individual answers so that it's less confusing.
1) The question says that QR is a perpendicular bisector of TS. This means that the length of TQ and QS is the same. Also, since both triangles TRQ and SRQ share the same side RQ, and the angle between the two segments is 90 degrees, the two triangles are congruent (RTQ and RSQ) using SAS.
2) Side RT and TS will have the same length since the two triangles are congruent. (2x+1) = (4x-3) --> -2x = -4 --> x = 2. We can conclude that x = 2.
3) Now that we know that x = 2, we can find the length of side RS by replacing the x with 2. 4(2)-3 is 5, so RS = 5.
4) We can use the Pythagorean theorem to find RQ (Hypotenuse^2 = Other two sides added after being squared individually). Since the hypotenuse of triangle RSQ is RS which is 5, and one side is 4, we can input those into our equation. (5)^2 = (4)^2 + (RQ)^2. --> 25 = 16 + (RQ)^2 --> 9 = (RQ)^2 --> RQ = 3.
5) Since the two triangles RTQ and RSQ are congruent, side TQ and SQ also have the same length, since CPCTC (Corresponding parts of congruent triangles are congruent). QS is 4, so TQ will also be 4. This means that ST will be 8 (4+4). ST = 8
Now that we have all the clues, all we need to do is choose True or False.
RS = 5 is TRUE
RS = 4 is FALSE
ST = 10 is FALSE
QR = 4 is FALSE
Why are there two solutions for the equation |6+y| = 2?
Explain.
Answer:
y=-4 and y=-8
Step-by-step explanation:
When you have an absolute value around something, you can remove it, expect it's like a square root, it's going to be a [tex]\pm[/tex]. Because 6+y could've been -2 and the absolute value just made it positive 2
So set 6+y equal to -2 and 2 to find the two solutions:
6+y = 2
y = -4
6+y = -2
y = -8
Hey there!
YOUR EQUATION: |6 + y| = 2
CONVERT THAT TO:
y + 6 = 2 OR y + 6 = -2
FIRST let’s solve for: y + 6 = 2
y + 6 = 2
SUBTRACT 6 to BOTH SIDES
y = 6 - 6 = 2 - 6
SIMPLIFY THAT!
y = 2 - 6
y = -4
Possible solution #1: y = -4
LASTLY let’s solve for: y + 6 = -2
y + 6 = -2
SUBTRACT 6 to BOTH SIDES
y + 6 - 6 = -2 - 6
SIMPLIFY THAT AS WELL!
y = -2 - 6
y = -8
Possible solution #2. y = -8
Therefore, your answer should be:
y = -4 or y = -8

If 7 litres of petrol will last 23 minutes in Dave's car, then how long will 25 litres last? Give your answer to the closest minute.
Answer:
25 liters will last 82 minutes.
Step-by-step explanation:
All you have to do is divide 23 by 7 to get the minutes per liter.
This will get 3.285714285714286.
Next you multiply 3.285714285714286 by 25 and you get 82.14285714285714.

The probability distribution for a
random variable x is given in the table.
Answer:
1
Step-by-step explanation:
The probability that a random variable has a particular value or a range of values is the sum of the probabilities associated with each of the values.
ApplicationAll of the x-values in the table are less than or equal to 20, so p(x≤20) is the sum of all of the probabilities in the table.
p(x≤20) = 0.20 +0.15 +0.05 +0.1 +0.25 +0.1 +0.15 = 1.00
The probability is 1 that x ≤ 20.
The sum of the two digits of a number is 9. If the tens digit is one-half the units digit, what is the number?
Let t = the tens digit, u = the units digit, and t+u = 9. Which of the following equations would complete the system?
t-u=1/2
t=1/2u
u=1/2t
Answer:
t=1/2u
Step-by-step explanation:
Since t=tens digit and u=units digit, as given in the equation that means that t+u=9. Since the tens digit is one-half the units digit that means: [tex]t=\frac{1}{2}u[/tex] since it's one half the units digit.
In the diagram, a circle centered at the origin, a right triangle, and the Pythagorean theorem are used to derive the equation of a circle, x2 + y2 = r2.
On a coordinate plane, circle Q is centered at the origin with radius r. Triangle P Q S is shown. Point Q is at (0, 0) and points P is at (x, y). The length of Q P is r, the length of P S is y, and the length of Q S is x. Angle P S Q is a right angle.
If the center of the circle were moved from the origin to the point (h, k) and point P at (x, y) remains on the edge of the circle, which could represent the equation of the new circle?
(h + x)2 + (k + y)2 = r2
(x – h)2 + (y – k)2 = r2
(k + x)2 + (h + y)2 = r2
(x – k)2 + (y – h)2 = r2
Based on the given information, the equation of this new circle is B. (x - h)² + (y - k)² = r²

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels at a rate of 65 miles per hour. The westbound train travels at a rate of miles per hour. How long will it take for the two trains to be miles apart
Answer:
It will take 1 hour and 24 minutes.
Step-by-step explanation:
Given that:
Eastbound train travels at a rate of 65 miles per hour and Westbound train travels at a rate of 85 miles per hour
So speed = 65 + 85 = 150 miles per hour
Total distance = 210 miles
We have to find the time, we know that
Distance = time * speed
OR
Time = distance / speed
Time = 210/150
Time = 1.4 hours
Or it can be written as:
Time = 1 hour 24 minutes

2x - y = 7.
2x + 4y = 12
Subtract both equations
-5y = -5
y = -5/-5
y = 1
From equation i
2x - y = 7.
2x - 1 = 7
2x = 7 + 1
2x = 8
x = 8/2
x = 4
Therefore, x = 4 and y = 1

Which type of statistics explains characteristics of variables found in a sample and describes, summarizes, and synthesizes collected data
Type of statistical characteristics of variables found in a sample and describes summarizes and synthesizes collected data is a. Descriptive.
Descriptive statistics are used to describe or summarize the characteristics of a sample or data set, such as a variable's mean, standard deviation, or frequency.
Descriptive statistics can be used to describe a single variable (univariate analysis) or more than one variable (bivariate/multivariate analysis). In the case of more than one variable, descriptive statistics can help summarize relationships between variables using tools such as scatter plots.

PLSS HELP geometry it's about relations within triangles. need help solving for variables
Using the definition of congruent triangles, the missing measurements are:
23. m = 7; LO = 14; NO = 14
24. x = 15; m∠QTS = 90°
25. p = 3; IJ = 15; KJ = 15
26. r = 3; UW = 48
27. y = 7; m∠DEF = 50°
28. m = 5; p = 10
What are Congruent Triangles?If two triangles are congruent, then all its corresponding sides and angles are equal.
23. The two triangles are congruent by SAS, therefore:
LO = NO
m + 7 = 2m
7 = 2m - m
7 = m
m = 7
LO = NO = m + 7 = 7 + 7 = 14
LO = 14
NO = 14
24. But triangles are congruent by SSS, therefore:
3x = 5x - 30
3x - 5x = -30
-2x = -30
x = 15
m∠QTS = 2(3x) = 6x = 6(15)
m∠QTS = 90°
25. Both triangles are congruent by ASA, therefore:
4p + 3 = 3p + 6
4p - 3p = -3 + 6
p = 3
IJ = KJ = 4p + 3 = 4(3) + 3 = 15
IJ = 15
KJ = 15
26. The two triangles are congruent by SAS, therefore:
5r + 9 = 8r
9 = 8r - 5r
9 = 3r
9/3 = r
r = 3
UW = 2(8r) = 16r = 16(3)
UW = 48
27. Both triangles are congruent by SSS, therefore:
3y + 4 = 5y - 10
3y - 5y = -4 - 10
-2y = -14
y = 7
m∠DEF = 2(3y + 4) = 6y + 8 = 6(7) + 8
m∠DEF = 50°
28. Both triangles are congruent by SSS, therefore:
2m = 10
m = 10/2
m = 5
2p - 5 = p + 5
2p - p = 5 + 5
p = 10
