Geometry - Triangle Proofs

The video tutorial explores three key postulates in geometry: Side-Side-Side (SSS), Side-Angle-Side (SAS), and Angle-Side-Angle (ASA). Through experiments and examples, it demonstrates how these postulates can be used to prove the congruence of triangles. The SSS postulate shows that triangles with three equal sides are congruent. The SAS postulate illustrates congruence with two sides and the included angle. The ASA postulate proves congruence with two angles and the included side. Each section provides practical examples and proofs to solidify understanding.
