You can move the points around. The segments on the right will always maintain that AB = DE and side across from the right angle is the hypotenuse.[br][br]Try to make a triangle.[br][br]If the triangle you make is green, then the triangles are congruent. If it is red then they are not.[br][br]Can you find a pair of non-congruent triangles?
What type of triangles are both figures?
Did knowing the hypotenuse, leg, and right angle provide enough pieces to make a congruent triangle? Were you able to find a non congruent triangle?
