He has decided to creale a pattern using mulfole pars of congrumt triangles. He creates two stencils for each so he can paint both triangles of each par at the same time. Unfortunately, his dog. Much, knocked over his box of stencis Some are even wrinked. Now Mr. Rose would like a quick way to be absolutely certain that congruent stencls get paired property. Give at least two methods that could be used to solve the problem without creating new stencis.
