Triangle Congruence Rules and Concepts

The video tutorial explains how to determine if two triangles are congruent. It introduces the concept of congruence, which means two shapes are identical in form and size. The tutorial covers three main rules for proving triangle congruence: Side-Side-Side (SSS), Side-Angle-Side (SAS), and Angle-Side-Angle (ASA). Each rule requires knowledge of specific sides and angles to establish congruence. The video emphasizes the importance of not skipping more than one unknown element when applying these rules.

What does the term 'congruence' mean in the context of triangles?

• Different in shape and size

• Different in shape but same in size

• Same in shape and size

• Same in shape but different in size

How many angles and sides does a triangle have?

• Four angles and three sides

• Three angles and two sides
