Question

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

Explanation:

Step1: Recall congruent - figure definition

Two figures are congruent if one can be mapped onto the other using rigid transformations (translations, rotations, reflections) without changing its shape and size.

Step2: Observe the two triangles

The two triangles have the same shape and size. We can translate the lower - left triangle to the upper - right position. A translation is a rigid transformation.

Answer:

Yes
