Rotation part two

What if we want to rotate a shape?

The shape PQRSTU is shown below. Point P on this shape is the same point P that we rotated through 90° in a clockwise direction about the origin

Below, P has been rotated through 90° clockwise about the origin to produce P′

To rotate all of PQRSTU, we need to rotate each point in the same way that we rotated point P. Let’s do this for point R next.

Continuing in this way, eventually, we rotate all of the points.

We can join the dots up and we have rotated the shape 90° clockwise around the origin
