Exploring a Rotation about the Origin

Observe how the triangle changes location as you manipulate the slider to change to angle of rotation.
1. Is this rotation going clockwise or counterclockwise?[br][br]2. Record the coordinates for each vertex when the triangle is rotated 90, 180, and 270 degrees.[br][br]Pre-image coordinates: A = (1,2); B = (5,3); C = (4,6)[br]Rotated 90 degrees: A' = B' = C' =[br]Rotated 180 degrees: A' = B' = C' =[br]Rotated 270 degrees: A' = B' = C' =[br][br]3. Decribe the change in the coordinates with a 90 degree rotation.[br][br]4. Decribe the change in the coordinates with a 180 degree rotation.[br][br]5. Decribe the change in the coordinates with a 270 degree rotation.[br][br]6. When the triangle is being rotated, what happens to the size and shape of the triangle?
