The shape moves 1 quadrant to the right on the coordinate plane.

90° Clockwise

The shape moves 1 quadrant to the left on the coordinate plane.

​​90° Counter
Clockwise

The shape moves 2 quadrant to the right on the coordinate plane.

180° Clockwise

The shape moves 2 quadrant to the left on the coordinate plane.

180° Counter
Clockwise

​Shape rotates 3 quadrants to the right ending up in the same quadrant as a 90° Counter-Clockwise Rotation

​​270° Clockwise → 90⁰ CCW

​Shape rotates 3 quadrants to the leftt ending up in the same quadrant as a 90° Clockwise Rotation

​​270° CCW → 90⁰ Clockwise

CL-X
x & y switch places
x becomes its opposite
-x → +x
+x → -x

(x, y) → (y, -x)

90° CLockwise

CO-Y
x & y switch places
y becomes its opposite
-y → +y
+y → -y

(x, y) → (-y, x)

90° COunter-clockwise

Algebraic representation Clockwise

x & y stay in their places
both x & y become their opposite
-x → +x
+x → -x
-y → +y
+y → -y
(x, y) → (-x, -y)
