Question

triangle abc is transformed to create triangle mnl. which statement is true? the transformation is rigid because corresponding side lengths and angles are congruent. the transformation is nonrigid because the three sides and the three angles in each triangle have different measures. the transformation is nonrigid because the two triangles have different names. the transformation is rigid because corresponding side lengths are congruent and corresponding angles are not congruent.

Explanation:

A rigid - transformation preserves side lengths and angles. Since corresponding side lengths and angles of triangle ABC and triangle MNL are congruent (as indicated by the markings), the transformation is rigid.

Answer:

The transformation is rigid because corresponding side lengths and angles are congruent.
