Triangle Congruence and Criteria

The video tutorial introduces the concept of congruence using practical examples, focusing on congruence of triangles. It covers the criteria for congruence, including SSS, SAS, ASA, and RHS, and explains how to determine congruence for lines, angles, and triangles. The tutorial includes a self-assessment section to reinforce learning.

What is the term used to describe two objects that are identical in shape and size?

• Similar

• Congruent

• Perpendicular

• Parallel

Which of the following is true for two congruent line segments?

What must be true for two triangles to be congruent according to the SSS criterion?

• Two sides and an angle are equal

• All sides are equal

• All angles are equal
