Question

Triangle PQR has the following coordinates:

P (-9,-12) Q(-6, -13) R(-7, -4)

Where is Q' after a rotation 90° clockwise?

Please write your answer as a coordinate: (x, y)

Answer 1

The coordinates of Q’ are (-13,6)

Explanation:

Here, we want to get the coordinates of the point Q’ obtained by rotating point Q at a degree of 90 clockwisely

Generally, we have the formula for the rotation as follows;

(x,y) will then (y,-x)

Thus,

(-6,-13) will become (-13, -(-6)) = (-13,6)
