Question

Rectangle EFGH has vertices E(1,-1), F(3,-5), G(7,-5), H(6,-1). If the shape is rotated 90 degrees clockwise about the origin, what are the coordinates of H'

Answer 1

The coordinates of H’ is (-1,-6)

Explanation:

Here, we want go get clockwise rotation about the origin

mathematically, if we had this kind of rotation, it would be that

(x,y) will turn to (y,-x)

So we have it that (6,-1 becomes)

(-1,-6)
