Mapping a Triangle to a Congruent Triangle Using Reflections

Mapping a Triangle to a Congruent Triangle Using 3 or Fewer Reflections

We demonstrate mapping any triangle to a congruent triangle using 3 or fewer reflections. If we assume that there is a Reflection Postulate that says that a reflection maps a preimage to a congruent image, then we can use this to prove the SAS congruence property as a theorem.
