Triangle ABC and triangle PQR are congruent with m∠P = 70°, m∠Q = 60°, and m∠R = 50°.

What is a transformation?

Transformation is the movement of a point from its initial location to a new location. Types of transformation are translation, reflection, rotation and dilation.

Reflection and translation is a rigid transformation and produces congruent figures. Hence:

Triangle ABC and triangle PQR are congruent with m∠P = 70°, m∠Q = 60°, and m∠R = 50°.
