Question

Two rigid transformations are used to map ΔABC to ΔXYZ. The first is a translation of vertex A to vertex X. What is the second transformation?

Answer 1

A. a reflection across the line containing AB

Answer 2

1. Two triangles can be mapped to each other only if they are similar.

2. So we are assuming similarity of the triangles.

3. First we translate vertex A to vertex X
Second, we rotate AC to XZ (or now AZ) , with an angle measure equal to that of angle CXZ
third we dilute the larger to the smaller so that they match.
