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. 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 are the steps to performing a 90 degree rotation?

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.

## What is the rule for a 90 degree rotation counter clockwise?

Let A (-5, 3), B (-4, 1), C (-2, 1) D (-1, 3) and E (-3, 4) be the vertices of a closed figure. If this figure is rotated 90° counterclockwise, find the vertices of the rotated figure and graph. Step 2 : Based on the rule given in step 1, we have to find the vertices of the rotated figure.

## How do you rotate a point 90 degrees clockwise?

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

## How do you rotate a point 90 degrees clockwise about the origin?

A rotation by 90° about the origin is shown. The rule for a rotation by 90° about the origin is (x,y)→(−y,x) .

## What is the angle of 90 degrees?

right angle-an 90 degree angle. obtuse angle-an angle between 90 and 180 degrees. straight angle-a 180 degree angle.

## How do you rotate a vector 90 degrees?

Normally rotating vectors involves matrix math, but there’s a really simple trick for rotating a 2D vector by 90° clockwise: just multiply the X part of the vector by -1, and then swap X and Y values.
