A student reasons about whether a pair of triangles are congruent by trying to map one onto the other using rigid transformations.

When we were first taught congruency of geometric figures, we directly began learning the various cases like SSS, SAS, AAS, RHS and ASA. But we were never taught rigid transformations!!! Thanks to Khan academy that they allowed me to fill this gap.
