Question

Triangle PQR is rotated 90 degrees counterclockwise about the origin to form the image triangle P'Q'R'. What are the vertices of triangle PQR

Answer 1

Hope this helps!

Explanation:

Triangle PQR has vertices P (3, 3), Q (5, -1), and R (1, -3). When triangle PQR is rotated 90 degrees counterclockwise about the origin to form the image triangle P’Q’R’, the vertices of the new triangle are P’(-3, 3), Q’ (1, 5), and R’ (3, 1)
