Method 1 of 3: Rotating a shape 90 degrees is the same as rotating it 270 degrees clockwise. The convention is that when rotating shapes on a coordinate plane, they rotate counterclockwise, or towards the left. You should assume this, unless it is noted in the problem that you need to rotate clockwise.

How do you rotate a shape 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.
What is a rotation of 180 degrees?
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). Worked-out examples on 180 degree rotation about the origin: 1.
How do you rotate the shape of a degree?
Rotating Shapes
- When rotating a shape by 90 degrees about the origin, each point (x,y) becomes (-y,x)
- When rotating a shape by 180 degrees about the origin, each point (x,y) becomes (-x,’-y)
- When rotating a shape by 270 degrees about the origin, each point (x,y) becomes (y, -x)
How do you rotate 90 degrees clockwise around a 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.
What is 360 rotation?
A full rotation is 360 degrees “Doing a 360” means spinning around completely once (spinning around twice is a “720”). “I gave the wheel one complete turn looking for holes” “It completed one cycle”, meaning it went around exactly once. “She went full circle on liking carrots”.
