Question

The coordinates of the vertices of figure MNOP are M(10, 12), N(23, 16), O(12, 17), and P(11, 25). Figure MNOP was rotated around the origin to produce figure MꞌNꞌOꞌPꞌ with vertices Mꞌ(12, −10), Nꞌ(16, −23), Oꞌ(17, −12), and Pꞌ(25, −11).

What was the degree of rotation?
° clockwise

Answer 1

The points M(10, 12), N(23, 16), O(12, 17), and P(11, 25) is located in Quadrant I.

The points Mꞌ(12, −10), Nꞌ(16, −23), Oꞌ(17, −12), and Pꞌ(25, −11) is located in Quadrant IV

So the degree of rotation is 90 degrees
