Triangle ABC is transformed to create triangle MNL.

Question illustration
A
The transformation is rigid because corresponding side lengths and angles are congruent.
B
The transformation is rigid because corresponding side lengths are congruent and corresponding angles are not congruent.
C
The transformation is nonrigid because the two triangles have different names.
D
The transformation is nonrigid because the three sides and the three angles in each triangle have different measures.
