HL Postulate Exploration
Directions
You can move the points around. The segments on the right will always maintain that AB = DE and side across from the right angles will always be equal to maintain HL congruence between the triangles.
Try to make a triangle.
If the triangle you make is green, then the triangles are congruent. If it is red then they are not.
Can you find a pair of non-congruent triangles?
