Question

which statement about the transformation is true? it is rigid because all side lengths and angles are congruent. it is rigid because no side lengths or angles are congruent. it is nonrigid because all side lengths are congruent. it is nonrigid because no side lengths or angles are congruent.

Explanation:

A rigid transformation (also called an isometry) is a transformation of the plane that preserves length. This means that after the transformation, the side - lengths and angles of the figure remain congruent. In the given triangles, since all side - lengths (as indicated by the marks) and angles are congruent, the transformation is rigid.

Answer:

It is rigid because all side lengths and angles are congruent.
