Triangle Congruence Theorems Modified
Use this applet to investigate triangle congruence theorems.
Click on one shortcut at a time. The two triangles you see on the screen are congruent. Is it possible to make non-congruent triangles by manipulating the orange triangle? Try and drag the vertices and change the angles to see if you can.
You will know you formed a triangle when the interior is filled in.
Are the two triangles still congruent?
