Questions for Clockwise Rotation: 1) Record the coordinates for triangle ABC. 2) Rotate triangle ABC 90 degrees clockwise. Record the new coordinates. What happened to the x and y coordinates? What happened to their signs? 3) With the triangle still rotated 90 degrees, look at the dotted lines. What type of angle do they form? 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. 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?
