Question

Angle PQR is formed by segments PQ and QR on the following coordinate grid:

Answer 1

Angle PQR is rotated 90 degrees counterclockwise about the origin to form angle P'Q'R'. Which statement shows the measure of angle P'Q'R'?

m∠P'Q'R' = 90 degrees
m∠P'Q'R' = 180 degrees
m∠P'Q'R' = m∠PQR
m∠P'Q'R' = 2 ⋅ m∠PQR
