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?
