## RD Sharma Class 9 Maths Congruent Triangles Solutions - Free PDF Download

Congruent Triangles are an important part of our everyday world, particularly for reinforcing many structures. Two triangles are congruent if they are absolutely the same in measure. This implies that the matching sides must be the same length and the matching angles must be the same size. The RD Sharma Class 9 Chapter 10 Solutions covers all important concepts and questions about Congruent triangles.

### Tips to Prepare for Exams Using RD Sharma Solutions of Class 9 Maths Chapter 10

These useful tips will help students to tackle all kinds of problems from the Congruent triangles chapter to score good marks in their exams.

• First, understand the definition of congruent triangles and different combinations of triangles.

• Since most of the problems will be of proving type involving diagrams. So students should be strong in their basic knowledge about triangles and their properties.

• Solve as many problems on congruent triangles to master the subject and to score good marks in board exams.

## What is the meaning of Congruence of Triangles in RD Sharma Solutions for Class 9 Maths Chapter 10?

According to the solutions of RD Sharma Solutions for Class 9 Maths Chapter 10, two triangles can be referred to as congruent triangles only when they are exact copies of each other and superposed or they cover each other completely. There are three criteria for two triangles being congruent:

• The corresponding three pairs of sides of the triangle are equal.

• The corresponding two pairs of sides and the angles corresponding between them are equal.

• The corresponding two pairs of angles and the sides corresponding between them are equal.

The theorem of ASA – Angle, Side, and Angle means that when we are solving the sum with two triangles, the two angles and one included side is equal. If this theorem is fulfilled, then the triangles are proved to be congruent.

## The Rules for assembling Triangles are as follows RD Sharma Solutions for Class 9 Maths Chapter 10 - Congruent Triangles:

• SSS (Side-Side-Side): The triangles are said to be parallel to each other when all the sides of the two triangles are equal.

• SAS (Side-Angle-Side): Both the triangles in the given sum will be congruent when the two sides and the inner angle of the triangle are equal to the corresponding sides and the inner angle of the other triangle.

• ASA (Angle-Side-angle): The triangles are bound to be congruent if two angles and the included side of one triangle are equal to the two corresponding angles and are placed on the other side of the triangle.

• RHS (Right angle - Hypotenuse-Side): The two triangles are said to be congruent if two triangles in right angles, the hypotenuse and any side of the triangle are equal to the hypotenuse and the other side of the other triangle.

## What is the necessity of making Revision Notes for Class 9 Maths Chapter 10 - Congruent Triangles?

Class 9 is a very crucial step in the academic life of every student as it forms the basis of Class 10 board examinations. Each chapter in the designed syllabus is very important to study. RD Sharma Solutions for Class 9 Maths Chapter 10 – Congruent Triangles has made it simpler for the students to prepare each exercise in Congruence of triangles. In this chapter, students will have a fundamental concept of the geometry of congruence. Revision notes are an important part of the process of the syllabus. You cannot study in a structured manner if your notes are not updated. The students will face numerous last moment confusions which will be obliterated only by the revision notes.  Scoring good marks and just passing the exams are two different things. And a student can score good marks in Class 9 Chapter 10 congruent triangles only through revising it repeatedly. Revision notes act as a mind-activating tool that enhances the learning power. Absorption of study material becomes easier and quicker while making notes.

## FAQs on RD Sharma Solutions for Class 9 Maths Chapter 10 - Congruent Triangles

1. What are congruent triangles?

If two angles and the included side of one triangle are congruent with the corresponding parts of another triangle, the triangles are congruent.

If two angles and the included side are the same in both triangles, the triangles are congruent.

2. How important is RD Sharma Solutions of Class 9 Maths Chapter 10?

It is so vital to study the congruence of triangles that it also helps us to draw conclusions regarding the congruence of polygons. We'll see how they correspond to each other in the six sections of a triangle, and how they have to be aligned to indicate congruence.

6. Which shows the two triangles associated with AAS?

The AAS rule states: If two angles and the excluded side of one triangle are equal to two angles and the excluded side of another triangle, then the triangles are congruent. In the diagrams below, if AC = QP, angle A = angle Q, and angle B = angle R, then the ABC triangle corresponds to the QRP triangle. All these are available in the RD Sharma Solutions for Class 9 Maths Chapter 10 – Congruent Triangles and Vedantu is the best source for downloading the solutions free of cost.

7. What congruence theorem can be used to prove that the ABC triangle is congruent with the DEC triangle?

Side-Angle-Side (SAS) property is used to show that the ABC triangle is congruent to the DEC triangle.  If the two sides in one triangle correspond to the two sides of the second triangle, and also if the angles are inserted together, then the triangles are aligned.

If the triangle is ABC and DEF, AB = DE, AC = DF, and angle A = angle D, then the ABC triangle corresponds to the triangle DEF.

AB = DE

BC = EF

CA = FD

Angle A = Angle D

Angle B = Angle E

Angle C = Angle F

(Of course, Angle A is short for angle BAC, etc.)
