Congruent figures: side lengths and angle measures

These figures are congruent. What is TR?

Since the figures are congruent, all sides have the same length.

According to the figure, JI = 61 ft. So, TR = 61 ft.

These figures are congruent. Find the measure of angle I.

Since the figures are congruent, all angles have the same measure.

According to the figure, m Q = 42°. So, m I = 42°.
