Triangle Congruence and Properties

The video tutorial covers the concept of triangle congruence, including its criteria and properties. It explains the different rules for proving congruence, such as SAS, ASA, SSS, and RHS. The tutorial also discusses the properties of triangles, including theorems about angles and sides, and explores inequalities within triangles. Practical applications of congruence in real-world scenarios are highlighted, and the lesson concludes with a summary of key points.
