Rule : When we rotate a figure of 90 degrees clockwise, **each point of the given figure has to be changed from (x, y) to (y, -x) and graph the rotated figure**. Let us look at some examples to understand how 90 degree clockwise rotation can be done on a figure.

## What happens when coordinates rotate 90 clockwise?

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

## What happens to the coordinates when rotated 180 degrees clockwise?

180 Degree Rotation. Rotation of a point through 180°, about the origin when a point M (h, k) is rotated about the origin O through 180° in anticlockwise or clockwise direction, it takes the new position M’ (-h, -k).

## Do you think that a 270 clockwise rotation is the same as a 90 counterclockwise rotation explain why or why not?

Answer: Yes, I think they are the same. One revolution is 360 degrees A 180 degree clockwise rotation is the same as a 180 counterclockwise rotation. The sum of the measures is 360. So moving in a clockwise direction for 270 degrees would end at the same place as moving 90 degrees in a counterclockwise direction.

## Is a 90 degree rotation clockwise or counterclockwise?

Since the rotation is 90 degrees, you will rotating the point in a clockwise direction.

## Is rotating 180 degrees clockwise different than rotating 180 degrees counter clockwise?

Yes, the formula for a 180° rotation about the origin is the same for both clockwise and counterclockwise.

## What is 90 degrees counterclockwise?

90 Degree Rotation When rotating a point 90 degrees counterclockwise about the origin our point A(x,y) becomes A ‘(-y,x). In other words, switch x and y and make y negative.
