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?
Look at the ordered pairs after each rotation.
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.
3. What is the rule for rotating 270 degrees counterclockwise (90 clockwise) about the origin? Change the original triangle to see if the rule stays true.
4. What is the rule for rotating 180 degrees about the origin? Change the original triangle to see if the rule stays true.
