Build Congruent and Not Congruent Triangles & Transform Polygons (Sabelko)

Build Two Congruent Triangles

I want you to build me two congruent triangles. Measure and label the side lengths using "units."

Build Me Three Unique Triangles

1. None of the triangles should be congruent.[br]2. You should build one of each type. If you need to review types watch video to help! [br]3. Use this video to help if needed! https://www.youtube.com/watch?v=JQUTVgT9RXY[br]4. Classify each triangle based on their side lengths.
