Problem
The letter F shown below is rotated 
clockwise around the origin, then reflected in the 
-axis, and then rotated a half turn around the origin. What is the final image?
Solution
The first rotation moves the base of the 
to the negative -axis, and the stem to the positive 
-axis. The reflection then moves the stem to the negative -axis, with the base unchanged. Then the half turn moves the stem to the positive axis and the base to the positive -axis, choice 
.
