Questions for Clockwise Rotation:[br][br]1) Record the coordinates for triangle ABC. [br][br]2) Rotate triangle ABC 90 degrees clockwise. Record the new coordinates. What happened to the x and y coordinates? What happened to their signs?[br][br]3) With the triangle still rotated 90 degrees, look at the dotted lines. What type of angle do they form?[br][br]4) Rotate the triangle ABC 180 degrees clockwise. Record the new coordinates. Compare the coordinates to the original coordinates of triangle ABC. Describe how they changed.[br][br]5) With the triangle still rotated 180 degrees, look at the dotted line that connects the two triangles. Is there an angle? How many degrees? What is its shape?
