HELP ME, ASAP I DONT GET THIS. PLS PLS PLS Angle PQR is formed by segments PQ and QR on the following coordinate grid: A coordinate grid is shown from positive 6 to negative 6 on the x-axis and from positive 6 to negative 6 on the y-axis. A line segment PQ is shown with P as ordered pair negative 1, negative 1 and Q as ordered pair negative 5, negative 4. Another line segment QR is shown with R as ordered pair negative 1, negative 4. 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'?

A. m∠P'Q'R' = 90 degrees
B. m∠P'Q'R' = 180 degrees
C. m∠P'Q'R' = m∠PQR
D. m∠P'Q'R' = 2 ⋅ m∠PQR
