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
