How to Determine if an Angle is Included or Not - Congruent Triangles

The video tutorial explains the concept of included angles, which are angles between two sides of a triangle. It discusses the side angle side (SAS) congruence criterion and provides examples to illustrate included angles. The tutorial also highlights the importance of ensuring angles are included between the sides when determining congruence, and explains why some triangles may not be congruent if the angles are not properly included.

What happens if you skip an angle when trying to prove triangles are congruent using the side-angle-side method?

Why is it important to understand the difference between included angles and skipped angles in triangle congruence?
