Problem Statement:
Can somebody please write the problem statement?
A helpful tip to thinking about this question
- we can describe all rotations by an angle
- we can not describe reflections by an angle
- each reflection can be described about the axis it is reflected
- when two reflections are done in a row, an angle between the axis of each reflection can be found
- this permutation can now be described by an angle
- thus it must also be a rotation
-zach
