Task 21: Real World Me. Rose is decorating one of his stields. 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.

One fun method Mr. Rose could use is the "Fold Test." He can take each stencil and fold it in half lengthwise. If the two halves perfectly overlap, he knows the stencils are congruent! It's like origami with a purpose—just make sure to keep an eye on that mischievous dog! Another clever approach would be the "Overlay Technique." Mr. Rose can stack two stencils on top of each other. If they align perfectly, then they’re a matching set! To add a twist, he could use contrasting colored paper for the stencils—like a little art project while ensuring he gets his congruent pairs right. Who said problem-solving can’t be a bit artistic?
