SSS Construction

Use the length tool to determine if the two triangles are congruent.
Move points A, B, and C around to change the lengths of the sides.
Move the second triangle on top of the first and determine if they two triangles are congruent.
Is there any way that you can make the two triangles NOT congruent?
