Triangles | Exercise 6.3 | Chapter 6 | Class 10 Maths | NCERT Solutions | CBSE | SR Academy

Welcome to SR Academy, your ultimate learning platform for Class 10 Maths NCERT explanations and exercise solutions!
In this video, we’ll cover Chapter 6 – Triangles (Exercise 6.3) from the NCERT Class 10 Mathematics textbook, explained in a clear and step-by-step manner.

This exercise focuses on the criteria for similarity of triangles, one of the most important and frequently asked concepts in CBSE Class 10 Board Exams. Understanding these criteria will help you solve geometry problems easily and accurately.

📖 Chapter Overview:

The Triangles chapter deals with the concept of similar figures and the properties of similar triangles.
In Exercise 6.3, you will learn about the different criteria used to prove the similarity of triangles and how to apply them in various questions and proofs.

The Criteria for Similarity of Triangles are:
1️⃣ AAA (Angle-Angle-Angle) Similarity: If two triangles have equal corresponding angles, then their corresponding sides are in the same ratio, and the triangles are similar.
2️⃣ SSS (Side-Side-Side) Similarity: If the corresponding sides of two triangles are in the same ratio, then their corresponding angles are equal, and the triangles are similar.
3️⃣ SAS (Side-Angle-Side) Similarity: If one angle of a triangle is equal to one angle of another triangle, and the sides including these angles are in the same ratio, then the triangles are similar.

These properties are essential for proving geometric relationships and solving various mathematical problems in the upcoming exercises.
