Question

Quadrilateral ABCD has vertices A(–5, 1), B(–5, 3), C(–1, 3), and D(–1, 1). Without graphing determine the coordinates of A'B'C'D' after rotating quadrilateral ABCD 90 degrees clockwise about the origin.

Answer 1

Answer is A i took the test thank you for helping me with this!

Explanation:

Answer 2
