The video tutorial covers the Side Angle Side (SAS) congruence theorem, explaining how two triangles can be proven congruent if two sides and the included angle are congruent. It includes a detailed proof of the theorem, examples of its application in different scenarios, and a real-life problem-solving exercise. The tutorial emphasizes understanding included angles and using the SAS theorem in various geometric contexts.

• To solve algebraic equations

• To understand the properties of parallel lines

• To prove the congruence of two triangles using two sides and the included angle

What is an included angle in a triangle?

• An angle that is always 90 degrees

• An angle formed by two sides of a triangle
