Rotations of Triangles about the Origin

1. What is true about the distance from the preimage to the origin AND the distance from the image to the origin?[br][br]Look at the ordered pairs after each rotation.[br]2. What is the rule for rotating 90 degrees counterclockwise (270 clockwise) about the origin? Change the original triangle to see if the rule stays true.[br]3.
