Triangle Congruence Theorems
Use this applet to investigate triangle congruence theorems.
Play around with the applet to investigate whether non-congruent triangles can be made when we fix certain lengths, or angles.
Click on one shortcut at a time. The two triangles you see on the screen are congruent. Is it possible to make more than one triangle with the given congruent pieces. You will know you formed a triangle when the interior is filled in. Are the two triangles still congruent?
For which shortcuts were you able to create a different triangle?
For which shortcuts were you not able to create a different triangle?
