Congruence of Triangles

This topic begins with an activity using postal stamps to test and make the students understand the meaning of congruency. This is followed by an explanation about the superposition of plane figures to test whether they are congruent.

With the help of this topic, we will learn about congruence among the line segments. It tells that the line segments with equal length are congruent to each other and its vice versa is also true. It also teaches us to represent congruent lines.

This topic discusses the congruence of angles. It tells that the angles which are equal either in degree measure or in radian measure are congruent angles. It also teaches us about the representation of congruency of angles.

This topic discusses the congruence of triangles. It deals with various properties of the congruence of triangles and how congruence of triangles is represented. It also highlights different types of congruence criteria.

This topic covers the criteria for congruence of triangles. The congruence criteria for the triangles are SSS (Side-Side-Side) criteria, SAS criteria, and ASA Criteria.
