Question

Tiangle D has been dilated to create triangle D′. Use the image to answer the question. image of a triangle labeled D with side lengths of 24, 32, and 40 and a second triangle labeled D prime with side lengths of 6, 8, and 10 Determine the scale factor used.

Answer 1

To find the scale factor, we can compare the corresponding side lengths of the two triangles.

The length of the corresponding sides in the two triangles are:

D: 24, 32, 40
D': 6, 8, 10

We can see that each side in D' is 1/4 the length of the corresponding side in D. Therefore, the scale factor used to dilate triangle D to create triangle D' is 1/4
