NCERT Solutions for Class 9 Maths Chapter 9 Circles  PDF Download
JEE Mains & AdvancedNCERT solutions for class 9 maths chapter 9 is a great way to help you learn the concept of circles. A circle is the collection of all points in a plane, which are equidistant from a fixed point in the plane. This boundary is called the circumference. The line connecting the center of the circle to any point on the circumference is called the radius. The area enclosed within the arc of the circle is referred to as the area of a circle. These properties of a circle are essential for you to grasp an understanding of circles. Thus, It is essential for students to have a thorough comprehension of this topic.
The topics mentioned in NCERT solutions for class 9 chapter 9 Circles are the foundation for learning many complex topics. With proper practice of all questions in these NCERT solutions, students will get to know the concepts related to Circles like Circumference, Diameter, Chord, Arc, Secant, Sector, Segment, Subtended Angle, etc. In addition to learning the fundamentals of this topic, students will also be able to put their knowledge into practice in real situations.
NCERT solutions for class 9 maths chapter 9 are prepared by a mathematics experts team to help students develop analytical thinking.

Important Topics covered in Chapter 9  Circles
Below are the main topics covered in our NCERT solutions for class 9 maths chapter 9 Circles.
NCERT solutions for class 9 maths chapter 9 will provide students with step by step instructions and explanations on each of the following topics:
9.1 Angle Subtended by a Chord at a Point 
9.2 Perpendicular from the Centre to a Chord 
9.3 Equal Chords and their Distances from the Centre 
9.4 Angle Subtended by an Arc of a Circle 
9.5 Cyclic Quadrilaterals 
9.1 Angle Subtended by a Chord at a Point  In this section, students are asked to draw a card in a circle. The line is then extended to another point that connects two line segments. Inside the circle, it creates a triangle. This is also referred to as the angle subtended at a point by a chord. If the chord lengths are equal, then the angles of the chords are equal, and vice versa.
9.2 Perpendicular from the Centre to a Chord  In this part of the lesson, students can practice drawing a perpendicular from the center of the chord.
9.3 Equal Chords and their Distances from the Centre  This part of the NCERT solutions for class 9 maths chapter 9 states that the length of a perpendicular is the distance between a point and a line. If the point is on a line, then the distance from the line to the point is zero.
9.4 Angle Subtended by an Arc of a Circle  NCERT solutions for class 9 maths chapter 9 is entirely concerned with Circles. if we draw two arcs congruent from the center, then they have to be equal.
9.5 Cyclic Quadrilaterals  If all the vertices of the quadrilateral are in the circle, then the quadrilateral is referred to as a Cyclic Quadrilateral.
Important Theorems Covered In NCERT solutions for Class 9 Maths Chapter 9  Circles
NCERT solutions for class 9 maths chapter 9 Circles have included some important theorems.

Theorem 1 : Equal chords of a circle subtend equal angles at the centre.

Theorem 2 : If the angles subtended by the chords of a circle at the centre are equal, then the chords are equal.

Theorem 3 : The perpendicular from the centre of a circle to a chord bisects the chord.

Theorem 4 : The line drawn through the centre of a circle to bisect a chord is perpendicular to the chord.

Theorem 5 : Equal chords of a circle (or of congruent circles) are equidistant from the centre (or centres).

Theorem 6 : Chords equidistant from the centre of a circle are equal in length.

Theorem 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 8 : Angles in the same segment of a circle are equal.

Theorem 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 (i.e. they are concyclic).
