Chapter 10 Circles - NCERT Solutions for Class 9 Mathematics CBSE - TopperLearning

Circle: A circle is the collection of all points in a plane, which are at a fixed distance from a fixed point in the plane. Diameter: It is the longest chord class 9 maths chapter 10 question answer video the circle.

Circumference: The length of complete circle is called its circumference. Arc: A piece of circle between two point is called class 9 maths chapter 10 question answer video. Segment: The region between a chord and either of its arcs is called a segment of circular region.

Equal chords of a circle subtend equal angles at the centre. If the angles subtended by two chords of a circle at the centre are equal, the chords are also equal. The perpendicular from the centre of a circle to a chord bisects the chord.

The line drawn through the centre of a circle to bisect a chord is perpendicular to the chord. There is one and only one circle passing through three non-collinear points.

Because, between chord and arc a segment is formed. Sector is the region which is formed between radii and arc. Similarly, BD is diameter of circle. So, these solutions are applicable class 9 maths chapter 10 question answer video all these boards. All the questions are explained well mats the theorems of circles and giving proper examples. In few questions some axioms of circles are also used as theorems.

Study Material vixeo What do understand by a circle? What are the components of a circle? What are the main Properties related to a circle? Important Theorems on Circles Class 9 Maths Chapter 10 Equal chords of a circle are equidistant from the centre and cords equidistant from the centre of a circle are equal. If two arcs of a circle are congruent, then their corresponding chords are equal and conversely if two chords of capter circle are equal, then their corresponding arcs are congruent.

Congruent arcs of a circle subtend equal angles at the centre. 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. Angles in the same segment of a circle are equal. Angle in a semi-circle is a right angle. The sum of either pair of opposite angles of a cyclic quadrilateral is and if the sum of a pair of opposite angles of a quadrilateral isthen the quadrilateral is chzpter.

The centre of a circle lies in interior of the circle. A circle has only finite number of equal chords. True or False? Because, there are infinite number of equal chords in a circle.

Sector is the region between the chord and anseer corresponding arc. Is it true or false? If diagonals of a cyclic quadrilateral class 9 maths chapter 10 question answer video diameters of the circle through the vertices of the quadrilateral, prove that it is a rectangle. AC is diameter of circle. Hence, points A, B, C and D lie on the same circle.

What are the main Properties related to a circle? Important Theorems on Circles Class 9 Maths Chapter 10 Equal chords of a circle are equidistant from the centre and cords equidistant from the centre of a circle are equal.

If two arcs of a circle are congruent, then their corresponding chords are equal and conversely if two chords of a circle are equal, then their corresponding arcs are congruent. Congruent arcs of a circle subtend equal angles at the centre. 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.

Angles in the same segment of a circle are equal. Angle in a semi-circle is a right angle. The sum of either pair of opposite angles of a cyclic quadrilateral is and if the sum of a pair of opposite angles of a quadrilateral is , then the quadrilateral is cyclic. The centre of a circle lies in interior of the circle. A circle has only finite number of equal chords. True or False?

Because, there are infinite number of equal chords in a circle. Students are mostly asked to prove the statements based on the axioms and theorems explained in the chapter. The properties of triangles such as inequalities, congruence, rules of congruence have been explained in this chapter. Students are also taught about the application f the congruence rules while solving the exercise questions.

These questions are designed to test your cognizance. In chapter 8 you will be introduced to Quadrilaterals and their various properties. A quadrilateral is a figure obtained by joints four distinct points on a plane. Students are provided in-depth knowledge about the topic in this chapter. These questions are based on your application skills and analysis skills.

You have studied the concept of quadrilaterals and triangles, now you will study specific quadrilaterals viz. Parallelograms and triangles in relation to the calculation of their area. Students are taught about the formulas for area calculation and the relationship between different geometric figures in this chapter.

In this chapter of Class 9 Maths, you will learn about circles. Definition of a circle, tangent, chord, arc, etc. Various other concepts such as the angle subtended by the arc of a circle, cyclic quadrilaterals, etc.

These questions are based on your numerical abilities, application skills, and memory-skills. Ex In this chapter, you will learn to construct triangles with the use of angle bisectors.

Students will be taught certain methods that are used for the construction of certain types of triangles. If diagonals of a cyclic quadrilateral are diameters of the circle through the vertices of the quadrilateral, prove that it is a rectangle.

If the non � parallel sides of a trapezium are equal, prove that it is cyclic. Two circles intersect at two points B and C. Solution: Since, angles in the same segment of a circle are equal. If circles are drawn taking two sides of a triangle as diameters, prove that the point of intersection of these circles lie on the third side.

They intersect at a point D, other than A. Let us join A and D. Thus, D lies on BC. Case � I: If both the triangles are in the same semi-circle. Join BD. DC is a chord. Case � II : If both the triangles are not in the same semi-circle. Prove that a cyclic parallelogram is a rectangle.

Since, ABCD is a cyclic quadrilateral. Thus, ABCD is a rectangle. Prove that the line of centres of two intersecting circles subtends equal angles at the two points of intersection. Two chords AB and CD of lengths 5 cm and 11 cm, respectively of a circle are parallel to each other and are on opposite sides of its centre.

If the distance between AB and CD is 6 cm, find the radius of the circle. Solution: We have a circle with centre O. Let r cm be the radius of the circle. The lengths of two parallel chords of a circle are 6 cm and 8 cm. If the smaller chord is at distance 4 cm from the centre, what is the distance of the other chord from the centre? Parallel chords AB and CD are such that the smaller chord is 4 cm away from the centre. Let the vertex of an angle ABC be located outside a circle and let the sides of the angle intersect equal chords AD and CE with the circle.

Proof: An exterior angle of a triangle is equal to the sum of interior opposite angles. Prove that the circle drawn with any side of a rhombus as diameter, passes through the point of intersection of its diagonals.
