Question

are these figures congruent? hint. use rigid transformations. no yes

Explanation:

Step1: Recall congruence definition

Two figures are congruent if one can be mapped onto the other using rigid - transformations (translations, rotations, reflections).

Step2: Analyze possible transformations

We can translate the upper - triangle downwards by 5 units. Then, we can reflect it over the x - axis. After these rigid transformations, the two triangles will overlap exactly.

Answer:

Yes
