NCERT Solutions for Class 9 Maths Chapter 7 – Triangles Exercise 7.3
Students have studied the AAA congruence and other congruence rule related to angle of a triangle in the previous two exercises. Now, here students will learn some more new Congruence rule which will be related to the sides of a triangle. These congruence rules are described in two theorems as mentioned below:
- Theorem 7.4 (SSS congruence rule): If three sides of one triangle are equal to the three sides of another triangle, then the two triangles are congruent.
- Theorem 7.5 (RHS congruence rule): If in two right triangles the hypotenuse and one side of one triangle are equal to the hypotenuse and one side of the other triangle, then the two triangles are congruent.
After this the examples are given in the NCERT book to illustrate them in a better way for students understanding. The question in the exercise are fully based on SSS and RHS congruence rule. So, the students should first go through the examples and then solve the exercise problems.
