|Rotation turns a figure about a fixed point, called the center of rotation. Rays drawn from the center of rotation to a point and its image form the angle of rotation. Rotations can be clockwise or counterclockwise.|
Coordinate Rules for Rotations about the origin:
When a point (a,b) is rotated counterclockwise about the origin, the following rules are true:
Examples of figures rotated counterclockwise direction 900, 1800 and 2700:
Directions: Use a graph paper and rotate the following figures for 900, 1800 and 2700 about the origin. Also list the coordinates of the vertices of the image:
Using above data and choose the correct answer. Also write at least 5 examples of your own.
