Question

What scale factor was used to make the image?

Answer 1

The scale factor is 3.

Explanation:

The first triangle's length is 1, and the height is 3. The second triangle's length is 3, and the height is 9. Therefore, the scale factor is 3.

Answer 2

There are 2 ways of solving this problem, either we can use the Pythagorean theorem to find the length of both sides and divide to find the scale factor or find the length of the base and divide to find the scale factor. We will go with the second way since its easier.

The base length of the smaller triangle is 1.

The base length of the larger triangle is 3.

Divide to find the scale factor.

3 / 1 = 3

Therefore, the scale factor is 3.

Best of Luck!
