Lesson: Congruent Triangles Mathematics • 11th Grade

In this lesson, we will learn how to prove that two triangles are congruent using either the side-angle-side (SAS), the angle-side-angle (ASA), the side-side-side (SSS), or the right angle-hypotenuse-side (RHS) criterion and determine whether angle-side-side is a valid criterion for triangle congruence or not.
