lesson 2: practice problems
problem 3
describe a rigid transformation that you could use to show the polygons are congruent.

Explanation:

Rigid transformations include translations, rotations, and reflections. To show the two triangles are congruent, we can first translate one triangle so that a corresponding vertex of the two triangles coincides. Then, we can rotate the translated triangle around the coincided - vertex to align the two triangles.

Answer:

First, translate one triangle so that a vertex coincides with the corresponding vertex of the other triangle. Then, rotate the translated triangle around the coincided vertex to make the two triangles coincide.
