Class 9 Maths Chapter 9 Practice Questions with Solution
What do understand by a circle?
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.
What are the components of a circle?
1. Diameter: It is the longest chord of the circle.
2. Circumference: The length of complete circle is called its circumference.
3. Arc: A piece of circle between two point is called arc.
4. Segment: The region between a chord and either of its arcs is called a segment of circular region.
Properties related to CIRCLE
1. Equal chords of a circle subtend equal angles at the centre.
2. If the angles subtended by two chords of a circle at the centre are equal, the chords are also equal.
3. The perpendicular from the centre of a circle to a chord bisects the chord.
4. The line drawn through the centre of a circle to bisect a chord is perpendicular to the chord.
5. There is one and only one circle passing through three non-collinear points.

Important Questions on 9th Maths Chapter 9
If diagonals of a cyclic quadrilateral are diameters of the circle through the vertices of the quadrilateral, prove that it is a rectangle.
AC is diameter of circle. Hence, ∠ADC = 90° and ∠ABC = 90° … (1) [∵ Angle in a semicircle is a right angle.] Similarly, BD is diameter of circle. Hence, ∠BAD = 90° and ∠BCD = 90° … (2) [∵ Angle in a semicircle is a right angle.] From the equation (1) and (2), ∠ADC =∠ABC = ∠BAD = ∠BCD = 90° Hence, ABCD is a rectangle.
Fill in the blank: The centre of a circle lies in _____________ of the circle.
The centre of a circle lies in interior of the circle.
A circle has only finite number of equal chords. True or False?
False. Because, there are infinite number of equal chords in a circle.
Sector is the region between the chord and its corresponding arc. Is it true or false?
Sector is the region between the chord and its corresponding arc. False. Because, between chord and arc a segment is formed. Sector is the region which is formed between radii and arc.
ABC and ADC are two right triangles with common hypotenuse AC. Prove that ∠CAD = ∠CBD.
Given: Triangle ABC and ADC are two right triangle on common base AC.
To prove: ∠CAD = ∠CBD.
Proof: Triangle ABC and ADC are on common base BC and ∠BAC = ∠BDC.
Hence, points A, B, C and D lie on the same circle.
[∵ 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.]
Therefore, ∠CAD = ∠CBD [∵ Angles in the same segments are equal]
Important Theorems on Circles Class 9 Mathematics Chapter 9
1. Equal chords of a circle are equidistant from the centre and cords equidistant from the centre of a circle are equal.
2. 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.
3. Congruent arcs of a circle subtend equal angles at the centre.
4. 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.
