Determine the coordinates of the vertices of the rotation image of the trapezoid ABCD (in the figure) if it is rotated 90 degrees clockwise about point Y.

Question

Determine the coordinates of the vertices of the rotation image of the trapezoid ABCD (in the figure) if it is rotated 90 degrees clockwise about point Y.

Answer 1

For every rotation of 90 degrees clockwise, (x,y) ----> (y, -x).

A is (4,7), so A' is (7, -4).

The rest are on you. Go!
