The video tutorial explains how to identify triangles that can be proven congruent using the angle-side-angle (ASA) method. It provides four examples, each demonstrating different scenarios where ASA can be applied, such as shared sides and vertical angles. The tutorial emphasizes the importance of identifying corresponding angles and the included side to establish congruence between triangles.

What is the primary focus of angle-side-angle proofs?

• Identifying congruent sides only

• Identifying congruent angles only

• Identifying congruent angles and the included side

• Identifying congruent triangles using any method
