Detour Proofs - Double Triangle Congruence

This geometry video tutorial focuses on detour proofs which is basically proving that two triangles are congruent twice. Triangle congruence theorems in this lesson include the SSS, SAS, and AAS postulates. This geometry video contains two examples on two column proofs with cpctc.
