Rotation Investigation

1) Below is a triangle that has been rotated 90° about the origin (point 0,0). Make a table of the coordinates of the original triangle ABC and the rotated triangle A'B'C'. Original Triangle ABC Rotated Triangle A’B’C’ A ( ) A' ( ) B ( ) B' ( ) C ( ) C' ( ) 2) Rotate the original triangle ABC 180°, 270°, and 360°. (Select the rotate object around point by angle button-box the given triangle and select the origin. Now change the angle.) 3) Make a table of values for each rotation. What do you notice about the coordinates of each rotation compared to the original coordinates? Can you come up with a rule for each rotation?
