Question

A dilation is applied to a triangle such that the sides of the image are 1.5 times the length of their corresponding sides in the original triangle. Then the angles of the image must be 1.5 times the size of the corresponding angles in the original triangle.

A) True
B) False

Answer 1

False. For the two triangles to be similar, their angles must be congruent to each other. This means that no matter how long the sides get, the angles stay the same.

Answer 2

I believe it is true.
