Question

One triangle in the diagram below can be mapped onto the other using two reflections. Identify the

lines of reflection that would map one onto the other. Can you map one triangle onto the other using
just one basic rigid motion? If so, explain.

Answer 1

You didn’t show the diagram so mirror lines can’t be identified.
Two reflections can be done as a rotation with a centre where the mirrors intersect.
If the mirrors are parallel then you can use a translation (slide) instead.
