In this video, Teacher Gone explains the Side-Angle-Side (SAS) congruence postulate, which states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent. The video covers the concept of included angles, demonstrates the application of the SAS postulate in proving triangle congruence, and provides problem sets for practice. The video concludes with a reminder to like and subscribe to the channel for more educational content.

What is the main topic of the video?

• Pythagorean Theorem

• Circle Theorems

• Side Angle Side Congruence Postulate

• Quadrilateral Properties

What does the SAS Congruence Postulate state?

• If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent.

• If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent.

• If three angles of one triangle are congruent to three angles of another triangle, then the triangles are congruent.

• If three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent.
