Sergei wants to prove that Triangle A B C is similar to Triangle F G H.

On a coordinate plane, triangle A B C has points (1, 1), (3, 3), (3, 1). Triangle F G H has points (4, 4), (12, 12), (12, 4).
Which would help him prove that? Check all that apply.
Measure angles A and F to show they are congruent.
Measure angles F and G to show they are congruent.
Use the right angle marks to show that angles C and H are congruent.
Use the grid or a ruler to show that A B = F G, B C = F G, and A C = F H.
Use the grid or a ruler to show that StartFraction F G Over A B EndFraction = StartFraction G H Over B C EndFraction = StartFraction F H Over A C EndFraction.

Answer:

Step-by-step explanation:Option (A) and (E) are correct.

We can prove  ΔABC and ΔFGH  are similar by AA criterion or by showing that the  ratio of corresponding sides are equal.

Step-by-step explanation:

Given : two triangles, ΔABC and ΔFGH and we need to prove both are similar to each other.

We have to choose the correct options from the given choices.

Two triangles are said to be similar if their the corresponding sides are in proportion and the corresponding angles are congruent to each other.

that is

also measure ∠A and  ∠F  to show they are congruent as ∠H= ∠C = 90°

This can be observed by looking at the image . So when both triangle are congruent we an show by AA similarity criterion that  ΔABC and ΔFGH  are similar.

Thus, option (A) and (E) are correct.

We can prove  ΔABC and ΔFGH  are similar by AA criterion or by showing that the  ratio of corresponding sides are equal.

Answer:

Step-by-step explanation:

Break down the figure into two shapes.

SHAPE A: The larger one. We can infer the size of the bottom is 6 cm because it's the same size as it's top counterpart. Same goes for the left side, which will have a measure of 7 cm.

SHAPE B: The smaller one. We're going to use the same method as we did with the first one, and infer the lengths of the other sides using the existing ones.

To calculate area, it's length times width.

SHAPE A: Its two side measures are 6 and 7, which equates to 42 cm^2.

SHAPE B: Its two side measures are 2 and 3, which equates to 6 cm^2.

If you add the two, the total area is 44 cm^2.

There is secretly a rectangle and a square. The rectangle is at the bottom and the square is at the top.

rectangle:
The bottom of the rectangle measures 9cm. The sides measure 2cm; 9x2=18
The rectangle measure 18.

Square:
The top measure 6cm. The side measures 5cm. 5x6=30
So now you add everything together. 30+18=48

You could find the rectangle and the square by just creating a simple line. Some of the numbers don’t matter for example 3cm and 7cm didn’t matter in this situation. Hope this helped!!

Orlo uses a spool of wire to make 15 necklaces.

At this rate, how many spools of the same size would he use to make 50 necklaces?

Answers

4 bc 50/15 =3.33333333 repeated so u would have to round up

he would use to make 50 necklaces 4 spools of the same size.

What is ratio?

The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.

Given this, Orlo uses a spool of wire to make 15 necklaces.

Since she requires 15 necklaces = 1 spool of wire

So, requirement for 1 necklace = 1/15 spool of wire

Thus,

requirement of wire for 50 necklace = 50/15 spool of wire

requirement of wire for 50 necklace = 10/3 spool of wire

requirement of wire for 50 necklace = 3.33 spool of wire

Therefore, 4 spools of the same size he would use to make 50 necklaces.
