# What is the transformation for 90 degrees clockwise?

Contents

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

## What is the transformation rule for rotating 90 degrees clockwise?

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.

## What is the algebraic expression for a rotation 90 degrees clockwise?

Rules of Rotation

The general rule for rotation of an object 90 degrees is (x, y) ——–> (-y, x). You can use this rule to rotate a pre-image by taking the points of each vertex, translating them according to the rule, and drawing the image.

## Is a 90 degree rotation clockwise or counterclockwise?

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

## How do you rotate a Preimage 90 degrees?

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.

## Is a 90 degree rotation the same as a reflection?

1 Answer. No, it is not possible. If you have a rectangle that is 2 units tall and 1 unit wide, it will be the same way up after a horizontal or vertical reflection. You can rotate a rectangle through 90 degrees using 2 reflections, but the mirror line for one of them should be diagonal.

## Which image shows a 90 degrees clockwise rotation about the origin?

When the point is rotated through 90° clockwise about the origin, the point M (h, k) takes the image M’ (k, -h). Therefore, the new position of point M (-2, 3) will become M’ (3, 2).

## What does a 90 degree counterclockwise rotation look like?

When we rotate a figure of 90 degrees counterclockwise, each point of the given figure has to be changed from (x, y) to (-y, x) and graph the rotated figure.
