Topics Covered in Exercise 10.2 Class 10 Mathematics Questions
NCERT solutions class 10 maths ex 10.2 questions on number of tangents from a Point on a circle, which have been elucidated by our qualified maths teachers on eSaral.
1. 
Number of Tangents from a Point on a Circle 
2. 
Theorem 10.2 

Number of Tangents from a Point on a Circle  For a point on a circle, we can observe three different cases of the tangent number. In this section, you will learn about the theorem and how to prove it, as well as the three different cases to figure out the number of tangents from a point on a circle.
Case 1  There is no tangent to a circle passing through a point lying inside the circle.
Case 2  There is one and only one tangent to a circle passing through a point lying on the circle.
Case 3  There are exactly two tangents to a circle through a point lying outside the circle.

Theorem 10.2  The lengths of tangents drawn from an external point to a circle are equal.
Tips for Solving Exercise 10.2 Class 10 chapter 10 Circles
Ex 10.2 circle is the last exercise of NCERT solutions class 10 maths chapter 10. Here are some of the important tips provided by subject experts of eSaral which must be remembered before solving the questions.

The most important thing to remember is that in order to answer the proof based questions, students will need to do detailed study on different topics and theorems, such as length of the tangent from an external point, the sector, the secant, and so on. Students will need to read the question carefully and divide it into multiple parts.

Ex 10.2 of NCERT solutions class 10 maths chapter 10 is composed of complex questions. Therefore, it is recommended that students visualize the problems and draw the figures.

Once students are familiar with properties, theorems and formulas, they can solve this exercise with ease and increase their precision in performing calculations.
