Question

Polygon ABCDE rotates 52º about the origin to create polygon
A′B′C′D′E′. If m< BCD = 31º, what is m< B' C' D' ?

Answer 1

Answer:

31°

Step-by-step explanation:

Rotations about the origin are rigid transformations, meaning that they preserve segment length and angle measure. Therefore, since ∠BCD and ∠B'C'D' are corresponding angles, we know that m∠BCD ≅ m∠B'C'D' = 31°.
