Question

Medal! I think its 90 degrees.

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 MOP with vertices M (12, 10), N (16, 23), O (17, 12), and P (25, 11).

What was the degree of rotation?

___ degress clockwise

Answer 1

Wow, someone just asked this..

Answer 2

lol....

Answer 3

(10, 12) - Point M
(12, -10) - Point M'

It was rotated by the rule:

(y, -x)

And 90 degrees clockwise rule is (y, -x)

So you are correct!
