Question

Describe the transformations that will map triangle A to triangle B and illustrate the similarity between the two triangles

Answer 1

the answer would be D

Answer 2

A) Reflect across y-->(5, 2), Translate 5 down-->(5, -3) ... nope. Cross off A
B) Reflect across x-->(-5, -2), reflect across y-->(-5, -2) ... nope
C) Translate 4 down -->(5,-2), rotate 180-->(-5, 2) ... nope
It must be D, but test just to be sure:
D) Reflect across x-->(-5, -2), rotate 90 counter-clockwise -->(2, -5) yes.


If you noticed that rotating B to be upright produced a mirror image of A, then you know that an odd number of reflections were involved and could eliminate answers B and C immediately.

Hope this helps
