Question

a horizontal line m is shown with two similar triangles, abc and def. how can triangle abc be transformed to result in triangle def? a a reflection across a vertical line b a 90 - degree rotation about point c c a dilation, then a translation to the right d a dilation, then a reflection across a vertical line

Explanation:

1. Similar triangles have the same shape but may differ in size. This implies a dilation is involved.
2. The orientation of the two triangles is such that a reflection across a vertical line (after dilation) is needed to map one to the other.

Answer:

D. a dilation, then a reflection across a vertical line
