# How do the coordinates change in a 90 rotation? ## How do the coordinates change in a 90 rotation?

90° clockwise rotation: (x,y) becomes (y,-x) 90° counterclockwise rotation: (x,y) becomes (-y,x) 180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y)

## What is the rule for rotation of 90 degrees on the coordinate axes?

Rotating by 90 degrees: When you rotate by 90 degrees, you take your original X and Y, swap them, and make Y negative. So from 0 degrees you take (x, y), swap them, and make y negative (-y, x) and then you have made a 90 degree rotation.

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). 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.

How do you rotate a 90 degree clockwise graph?

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 figure 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) .

### How do you calculate a 90 degree rotation?

– Take a seat and then roll back, curl chin to chest. Place your hands behind your head with your elbows wide. – Extend your legs on the diagonal, with your toes pointed. – Pull the knees into the chest as you crunch upwards and close the elbows, then extend the legs as the elbows open wide again. – Perform 2 sets of 15-20 reps.

What is the formula for rotation of 90 degrees?

The rule/formula for 90 degree clockwise rotation is (x, y) —> (y, -x). After applying this rule for all coordinates, it changes into new coordinates and the result is as follows: I believe that the above graph clears all your doubts regarding the 90 degrees rotation about the origin in a clockwise direction.
