NCERT Solutions for Class 10 Maths Chapter 6 Exercise 6.2

To prepare for Class 10 Maths Exercise 6.2, emphasize understanding and applying the Basic Proportionality Theorem (also known as Thales’ Theorem). The problems in this exercise focus on using this theorem to solve for unknown sides of triangles. Make sure you can recognise when a line divides two sides of a triangle proportionally and how to use the theorem to solve various geometric problems. Start by practicing simpler problems that involve drawing parallel lines and calculating ratios of corresponding sides.

Work on more complex applications of the Basic Proportionality Theorem, such as problems that involve multiple steps or additional geometric principles like midpoints and parallel lines. Review the proofs provided in the chapter and attempt to write them in your own words. Understanding the logic behind the proofs will help you answer related questions effectively during exams. Focus on solving examples that require you to apply the theorem in different geometric configurations, as this will give you confidence in handling various problem types during your preparation.

A few questions can be solved directly by similarity theorems, but both the methods should be known as some time it is asked to do with Thales theorem only.

Exercise 6.2 is based on Thales Theorem (Basic Proportionality Theorem – BPT) and its converse. In Questions 1 and 2, we have to simply find the ratio of sides and apply the converse of BPT. Question 3 and 4 are direct application of Thales theorem. In Question 5 and 6, first apply BPT and then converse to prove the required things. Similarly questions 7, 8, 9 and 10 can be solved by using Thales as well as its converse. Question number 10 can be solved on the basis of similarity also, which will we study in Exercise 6.3.

Basic Proportionality Theorem: If a line is drawn parallel to one side of a triangle to intersect the other sides in distinct points, the other two sides are divided in the same ratio. [BPT is also known as Thales Theorem. The converse of the Thales theorem is also important to solve the questions.]
