Answer 1

Answer: 1.
`(1)/(3)` 2. 3 3. 9

Explanation:

Scale factor is the number being multiplied to see how the shape has has grown or shrunk compared to the original figure. We can do this by using the side lengths given.

What scale factor was used to dilate Triangle B to A?

If you look at triangle B, we can see a length of 3 units across the top.

In triangle A, you can see a length of 1. To go from B to A, we want to divide by 3. When translated, divide by 3 is the same as multiplying by
`(1)/(3)`.

Therefore, the scale factor is
`(1)/(3)`.

What scale factor was used to dilate Triangle B to C?

If you look at triangle B, we can see a length of 3 units across the top.

In triangle C, you can see a length of 9. To go from B to C, we want to multiply by 8.

Therefore, the scale factor is 3.

What scale factor was used to dilate Triangle A to C?

If you look at triangle A, we can see a length of 1 units across the top.

In triangle C, you can see a length of 9. To go from B to C, we want to multiply by 9.

Therefore, the scale factor is 9.
