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 to 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
