Drag and rotate the triangles to get matching sides together. It may be necessary to press the FLIP button to flip one triangle over before you can match all three sides. If the triangles are congruent, when you have matched sides the colors will switch, ending in a green triangle.

Definition and properties of congruent triangles - testing for congruence ... Congruent triangles can also have a common side or vertex that is shared by both triangles. For example in the figure below, the two triangles have the side QR in common and are congruent. Note that they are also reflections (mirror images) of...

All of the following triangles are congruent! ... Basically, the term congruent means that two or more things are the exact same size and shape. ... If we took any one of these triangles and flipped it over and/or rotated it, we'd be able to fit it right on top of any of the others!
