This geometry video tutorial provides a basic introduction into triangle congruence theorems. It explains how to prove if two triangles are congruent using the SSS, SAS, ASA, and AAS postulate using two column proofs. Here is a list of topics contained in the statements and reasons of the two column proofs: Definition of midpoints, reflexive property, congruent angles, perpendicular lines, right angles, vertical angles, supplements of congruent angles, angle bisectors, triangles in circles, overlapping triangles, addition property of equality, segment addition, definition of congruent segments, and segment trisectors. This video contains plenty of examples and practice problems.
