A pointer points up. A quarter turn is 90 degrees.
After one quarter turn it points to the right.
Two quarter turns are 2 times 90. That is 180 degrees, and the pointer points down.
The pointer makes 3 quarter turns. How many degrees is that?
Answer and working
Correct! 3 times 90 is 270 degrees. The pointer points to the left.
3 × 90 = 270
