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 rigid because corresponding side lengths are congruent and corresponding angles are not congruent. the transformation is nonrigid because the two triangles have different names. the transformation is nonrigid because the three sides and the three angles in each triangle have different measures.

Explanation:

Step1: Recall rigid - transformation definition

A rigid transformation (translation, rotation, reflection) preserves side - lengths and angles.

Step2: Analyze the given triangles

From the markings on the triangles, corresponding side - lengths and angles are congruent.

Answer:

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