Step 1:
Similar triangles are triangles that have the same shape, but different sizes. The corresponding angles are congruent and the sides are in proportion. Corresponding angle are angles in two different triangles that are “relatively” in the same position.
Step 2
Angle A is congruent to angle D
Angle B is congruent to angle E
Angle C is congruent to angle F.
Final answer
The measure of the angle C = 63
