# How to rotate a figure 90 degrees clockwise about a point?

Rotation helps us to align the figures in the direction along with a fixed point.

## Answer: To rotate the figure 90 degrees clockwise about a point, every point(x,y) will rotate to (y, -x).

Let's understand the rotation of 90 degrees clockwise about a point visually.

**Explanation:**

If R(x, y) is a point that needs to be rotated about the origin, then coordinates of this point after the 90° rotation will be **R'= (y, -x)**

When rotated through 90° about the origin in the clockwise direction, the new position of point P (2, 3) will become P' (3, -2)

So, each point has to be rotated and new coordinates have to be found. Then we can join the points and find the new positioned figure.
