WebProof. The homomorphic image of a dihedral group has two generators ˆa and ˆb which satisfy the conditions ˆaˆb = ˆa - 1 and ˆan = 1 and ˆb2 = 1, therefore the image is a dihedral group. For subgroups we proceed by induction. When n = 1 the result is clear. Now suppose that D2 n has some proper subgroup H that is not dihedral or cyclic.

Web3. Relations between rotations and reflections The rigid motions rand sdo not commute. Their commutation relation is a fundamental formula for computations in D n, and goes as follows. Theorem 3.1. In D n, (3.1) srs 1 = r 1: Proof. A short proof comes from rsbeing a re ection: (rs)2 = 1 )rsrs= 1 )srs= r 1, and s= s 1 since shas order 2.
