This video tutorial covers the concept of triangle congruence, explaining that congruent triangles have equal angles and side lengths. It introduces the congruence symbol and the importance of order in congruent statements. The video details four main congruence theorems: Side-Side-Side (SSS), Side-Angle-Side (SAS), Angle-Side-Angle (ASA), and Angle-Angle-Side (AAS). Each theorem is explained with examples, emphasizing the conditions under which triangles are congruent. The tutorial concludes with practice problems to apply these theorems.

What does the congruence symbol represent?

• Exact equality in shape and size

• Difference in angles only

• Inequality between shapes

• Similarity in shapes only
