Conditions of congruent triangles
In this lesson, we will learn about the conditions under which we can say that two triangles are congruent.
Prove triangles are congruent
In this lesson, we will learn how to prove that two triangles are congruent. We will investigate four different conditions involving observation and comparison of the angles and sides of each triangle. If any condition is met, we can determine that the triangles are congruent.
