Question

ebcd ≅ pqrs. what is m∠r?

Explanation:

Step1: Recall property of congruent polygons

Congruent polygons have equal - corresponding angles.

Step2: Identify corresponding angles

Since \(EBCD\cong PQRS\), \(\angle R\) corresponds to \(\angle E\).

Step3: Find the measure of \(\angle E\)

Given that \(m\angle E = 91^{\circ}\), then \(m\angle R=m\angle E\).

Answer:

91
