# NCERT Solutions for Class 9 Maths Chapter 7 Exercise 7.3 Triangles - PDF Download

Class 9 NCERT solutions for class 9 math chapter 7 ex 7.3 provides an overview on some more triangle congruence rules. This exercise concentrates primarily on the SSS (Side Side side Congruence Rule) and the RHS (Right Angle-Hypotenuse-Side Congruence Rule). Class 9 maths chapter 7 exercise 7.3 NCERT solutions is a proof-based exercise that consists of five questions. It is designed to assist students in studying and practicing these two rules through the use of examples and questions that are explained in detail in NCERT solutions.

In order to assist students in their study, we have compiled the solutions to each of the questions in the PDF format, accompanied by comprehensive explanations. Students can download the NCERT solutions for class 9 maths chapter 7 ex 7.3 free PDF by following the link on eSaral website. These solutions are also prepared by the most qualified teachers of eSaral.

NCERT solutions will provide students with all the concepts, definitions and theorems in this topic as well as the examples. NCERT solutions are trusted resources created by experts in this field to increase students’ math skills.

## Topics Covered in Exercise 7.3 Class 9 Mathematics Questions

Ex 7.3 class 9 maths chapter 7 is mainly concerned with the properties and theorem of triangles, their congruence, and similarity. You will learn these topics and concepts in detail on eSaral.

 1 Some more Criteria for Congruence of Triangles Theorem 7.4 Theorem 7.5
1. Some more Criteria for Congruence of Triangles

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. RHS stands for Right angle - Hypotenuse - Side

## Tips for Solving Exercise 7.3 Class 9 Chapter 7 Triangles

By practicing with NCERT solutions class 9 chapter 7 ex 7.3, students will be able to acquire the correct methodology to solve the questions based on triangle congruence.

1. It is essential for students to concentrate on the relevant theorems and properties outlined in chapter 7 ex 7.3 in order to remember the facts and concepts, as well as to solve the questions. This will enable them to adopt the appropriate approach to prepare for the exam.

2. Acquiring an in-depth understanding of essential concepts will allow students to develop the necessary problem-solving skills to address the problem presented in this exercise.

3. Students should also solve the questions provided in NCERT solutions to understand the exercise questions more effectively.

## Importance of Solving Ex 7.3 Class 9 Maths Chapter 7 Triangles

Here, students will learn a few more new congruence rules, which are related to the two sides of the triangle. These congruence rules are defined by two theorems. Students will gain a thorough understanding of these theorems by answering the questions in ex 7.3.

1. Our subject experts provide students with an in-depth understanding of the congruent triangle concept in ex 7.3 in class 9 maths. This is based on the RHS criteria and the SSS criteria.

2. Class 9 maths ex 7.3 solutions provides students with step-wise solutions to solve problems to help them understand the concepts clearly.

3. Ex 7.3 class 9 maths helps students get ready for their exams by providing them with a variety of questions  that they might face during their exams.

4. Class 9 maths ex 7.3 chapter 7 NCERT solutions are available on eSaral in PDF format, You can download these PDFs and work through each of these questions one at a time.

Question 1. What are the new criteria for triangle congruence in ex 7.3?

Answer 1. There are two criteria for triangle congruence.

1. The RHS (Right angle-Hypotenuse-Side) congruence.

2.  The SSS (Side Side Side) congruence.

Question 2. What do you mean by RHS criteria for congruence in chapter 7 ex 7.3?

Answer 2. 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.
