The triangles are congruent if all three sets of comparable sides are present. The side-side-side shortcut is a congruence technique (SSS). Side-angle-side (SAS), which uses two sets of sides and an angle between them that is known to be congruent, is another shortcut.
SSS, which stands for "side, side, side," denotes that there are two triangles with identical angles on all three sides. The triangles are congruent if their third sides are the same as those of another triangle. The triangles are congruent if two pairs of corresponding angles and the included sides are both true. This standard is called angle-side-angle (ASA).
Angle-angle-side (AAS) is another criterion that takes into account the congruence of two pairs of angles as well as the non-included side. SSS stands for "side, side, side," which signifies that we have two triangles with equal sides on all three sides. SAS, ASA, and AAS are acronyms for these rules. "Side, Angle, Side" stands for two triangles whose two sides and one included angle are known to be equal.

What ratio does the point 1 a divided the join of (- 1/4 and 4 1 )? Also find the value of a?
Using the provided values for the points and the slope, With the formula of slope we can calculate the value of a = 14/5 =2.8 and the ratio as
1:1.49 .
What do you mean by slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction. Divide the difference in elevation between two points by the distance between them to find the percent slope, then multiply the result by 100. The term "rise" refers to the difference in elevation between two sites. The run is the separation between the points. Percent slope is therefore equal to (rise / run) x 100.
What do you mean by ratio?A ratio in mathematics demonstrates how many times one number is present in another. For instance, if a dish of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six. Similarly, the ratio of oranges to the total amount of fruit is 8:14, while the ratio of lemons to oranges is 6:8.

What are the 3 steps to finding an inverse function?
Rewrite f(x)= as y in step one, Swap X and Y in step one, then solve for y in step three.
What is multiplicative inverse ?A number that, when multiplied by a number x, produces the multiplicative identity 1, or 1/x or x1, is known as a multiplicative inverse or reciprocal in mathematics. B/a is the multiplicative inverse of the fraction a/b. Divide 1 by the real number to find its multiplicative inverse. As an illustration, the reciprocal of 5 is 1/5 (1/5 or 0.2), whereas the reciprocal of 0.25 is 1 divided by 0.25 (1 divided by 0.25 = 4) One of the most straightforward instances of a function that is its own inverse is the reciprocal function, or f(x), which transfers x to 1/x (an involution).Since no real number multiplied by 0 yields 1, zero does not have a reciprocal in the real numbers (the product of any number with zero is zero). The reciprocals of all real numbers, except zero, are real; the reciprocals of all rational numbers, except zero; and the reciprocals of all complex numbers, save zero.Hence, Rewrite f(x)= as y in step one, Swap X and Y in step one, then solve for y in step three.

What equation is perpendicular to Y =- 3x 4?
Equation y = -3x is perpendicular to Y =- 3x - 4.
Describe perpendicular.A perpendicular is a straight line in mathematics that forms a right angle (90 degrees) with another line. In other words, two lines are perpendicular to one another if they connect at a right angle. In every case, perpendicular lines cross or intersect. Any two perpendicular lines will always have an angle of 90 degrees.
Given
y = -3x - 4
Using slope intercept form.
y = mx + b
The reciprocal of the slope of the perpendicular line is negative.
By doing this, you alter the slope's sign to the opposite, in this case to 3. The slope of the perpendicular line is then equal to 1/3 by finding the reciprocal by flipping the denominator and numerator.
Equation y = -3x is perpendicular to Y =- 3x - 4.

By what number must you multiply each side of the equation 45x=8 to produce the equivalent equation x = 10?.

For this case, we have the following equation:

We must find a number that when multiplied on both sides of the equation, as a result:
x = 10x
So, if we multiply 8 * 5 = 40
Now, the left side must also be multiplied by 5 to not alter the equation:

What is the set of all x values?
The range is the set of all "y" values in an ordered pair, while the domain is really the set of all "x" values.
What is defined as the term called domain?Keep in mind which ordered pairs are represented by the following symbols: (x, y).
List all the x values first from relation to determine the domain when examining a set of ordered pairs. List each of the y values first from ordered pairs to determine the range. Repeated values that fall inside the domain or range need only be listed once. Each x value in a relation must have a unique value for the y value for it to be a function.A collection of ordered pairs isn't a function if an x value has had more than one y value associated with it, as as in the relation (4, 1), (4, 2), where the x value of 4 has y values of 1 and 2.
Thus, If there is only one y-value for every x-value, then the relation is called a function.

Why does AAS congruence work?
Angle-Angle-Side is abbreviated as AAS. The triangles are said to be congruent when two angles and a non-included side of one triangle match the corresponding angles and sides of another triangle. AAS congruence may be demonstrated with a few simple methods.
When two triangles in geometry are the same size and shape, they are said to be congruent. The Angle-Angle-Side (AAS) congruence theorem is one of several approaches to demonstrate that two triangles are congruent.
According to the AAS congruence theorem, triangles are congruent if two angles and the side that connects them in one triangle are congruent with two angles and the side that connects them in another triangle. This is how this theorem is expressed:
If ∠A = ∠E, ∠B = ∠F, and AB = EF, then ∆ABC ≅ ∆DEF
In other terms, triangles ABC and DEF are congruent if two angles and the side between them in triangle ABC are equivalent to two angles and the side between them in triangle DEF.

How do you know if a function is positive or negative?
A function is positive if the output values are greater than the input values and negative if the output values are less than the input values.
To determine if a function is positive or negative, you must first look at the output values of the function. If the output values are greater than the input values, then the function is positive. This means that the output values increase as the input values increase. Conversely, if the output values are less than the input values, then the function is negative. This means that the output values decrease as the input values increase. For example, if a function has an input value of 3 and an output value of 5, then the function is positive because the output is greater than the input. On the other hand, if the same function had an output value of 1, then the function would be negative because the output is less than the input. In summary, a function is positive if the output values are greater than the input values and negative if the output values are less than the input values.
