# NCERT Solutions for Class 10 Maths chapter 6 Exercise 6.3 Triangles - PDF

Class 10 NCERT solutions for class 10 maths chapter 6 ex 6.3 Triangle shows the requirements for proving the similarity of the triangle. These three critical theorems, also referred to as Angle-angle-angle (AAA, Angle-side-angle (ASA) and Side-side-side (SSS). Triangle can be proven to be equivalent by meeting these three criteria.

NCERT solutions class 10 maths chapter 6 ex 6.3 consists of 16 questions covering all aspects of the theorems mentioned above. Students will be expected to observe the figure presented in the questions to ensure that they are able to effectively apply the fact where necessary.

## Topics Covered in Exercise 6.3 Class 10 Mathematics Questions

Class 10 maths ex 6.3 is based on the concept of similarity between different triangles in NCERT solutions.

 1 Criteria for Similarity of Triangles 2 Theorem 6.3 3 Theorem 6.4 4 Theorem 6.5
1. Criteria for Similarity of Triangles - If the angles of two triangles are the same and the corresponding sides are also the same, then they're said to be similar.

Important theorems are covered in this exercise.

1. Theorem 6.3 - If in two triangles, corresponding angles are equal, then their corresponding sides are in the same ratio (or proportion) and hence the two triangles are similar.

This criterion is referred to as the AAA (Angle–Angle–Angle) criterion of similarity of two triangles.

1. Theorem 6.4 - If in two triangles, sides of one triangle are proportional to (i.e., in the same ratio of ) the sides of the other triangle, then their corresponding angles are equal and hence the two triangles are similar.

This criterion is referred to as the SSS (Side–Side–Side) similarity criterion for two triangles.

1. Theorem 6.5 - If one angle of a triangle is equal to one angle of the other triangle and the sides including these angles are proportional, then the two triangles are similar.

This criterion is referred to as the SAS (Side–Angle–Side) similarity criterion for two triangles.
