Real World

Mr. Rose is decorating one of his shields. He has decided to create a pattern using multiple pairs of congruent triangles. He creates two stencils for each so he can paint both triangles of each pair at the same time. Unfortunately, his dog, Much, knocked over his box of stencils. Some are even wrinkled. Now Mr. Rose would like a quick way to be absolutely certain that congruent stencils get paired properly. Give at least two methods that could be used to solve the problem without creating new stencils.
