Topics Covered in Exercise 9.3 Class 9 Mathematics Questions
Exercise 9.3 is based on the concepts included in the chapter which mainly covers the concept of the angle subtended by an arc of a circle and the cyclic quadrilaterals. You can check these concepts in detail mentioned below.
1. 
Angle Subtended by an Arc of a Circle 
Theorem 9.7 Theorem 9.8 Theorem 9.9 
2. 
Cyclic Quadrilaterals 
Theorem 9.10 Theorem 9.11 

Angle Subtended by an Arc of a Circle
 If two chords of a circle are equal, then their corresponding arcs are congruent and conversely, if two arcs are congruent, then their corresponding chords are equal.
 Congruent arcs (or equal arcs) of a circle subtend equal angles at the centre
These abovementioned statements are true to the reference of angle subtended by an arc of a circle. You can find the detailed solutions of these statements in chapter 9 class 9 maths textbook.
Here are some important theorems associated with the topic angle subtended by an arc of a circle.

Theorem 9.7: The angle subtended by an arc at the centre is double the angle subtended by it at any point on the remaining part of the circle.

Theorem 9.8: Angles in the same segment of a circle are equal.

Theorem 9.9: If a line segment joining two points subtends equal angles at two other points lying on the same side of the line containing the line segment, the four points lie on a circle
2. Cyclic Quadrilaterals  If all the vertices of a quadrilateral lie in the circumference of a circle, then it is called a cyclic quadrilateral.
Here are some important theorems associated with the topic cyclic quadrilaterals.

Theorem 9.10: The sum of either pair of opposite angles of a cyclic quadrilateral is 180º.

Theorem 9.11: If the sum of a pair of opposite angles of a quadrilateral is 180º, the quadrilateral is cyclic.
Tips for Solving Exercise 9.3 Class 9 Chapter 9 Circles
Regular practice of the questions and examples included in NCERT solutions class 9 maths chapter 9 ex 9.3 can be beneficial in achieving a comprehensive solutionoriented approach to solving each question. Here are some important tips on how to solve questions to score high marks.

Students will have a thorough understanding of the theorems when they follow the step by step solution to the questions provided in NCERT solutions class 9 chapter 9 exercise 9.3.
