Question

Need help ASAP. The triangle undergoes a dilation. Which set of side lengths could the new triangle have if it is similar to the original?

Answer 1

The answer is C.

Explanation:

Dilation is a way of creating a similar shape. This is either an enlarged or shrunken version of the original triangle. All the lengths have to go under the same scale factor. We have to divide each dimension. Let's do this one at a time. A. 6/3 = 2 12/9= 1.3 continued. A is ruled out. Let's try B. 6/7 = 0.85 12/13=0.92 B is ruled out. C. 6/8 = .75 12/16= 0.75 looking good so far 15/20=0.75. Here we find our answer.
