Ex Fill in the blanks. Solution: i interior ii exterior iii diameter iv semicircle v the chord vi three. Write True or False. Give reason for your answers. Recall that two circles are congruent, if they have the same radii. Prove that, if chords of congruent circles subtend equal angles at their centres, then the Class 9th Ch 10 Maths Q2 chords are equal. Draw different pairs of circles. How many points does each pair Class 9th Ch 10 Maths Q2 have in common? What is the maximum number of common points? Solution: Let 9th 10 Q2 Maths Ch Class us draw different pairs of circles as shown below: We have.

Suppose you are Class 10 Ch Maths 9th Q2 given a circle. Give a construction to find its centre. Solution: Steps of construction : Class 9th Ch 10 Maths Q2 Step I : Take any three points on the given circle. Let these points Class 9th Ch 10 Maths Q2 be A, B and C. If two circles intersect at two points, prove that their centres lie on the perpendicular bisector of the common chord.

Two circles of radii 5 cm and 3 cm intersect at two points and the distance between their centres is 4 cm. Find the length of the common chord. Let PQ be the common chord. If two equal chords of a circle intersect within the circle, prove that the segments of one chord are equal to corresponding segments of the other chord. Join OE. If two equal chords of a circle intersect within the circle, prove that the line joining the point of intersection to the centre makes equal angles with the chords.

Solution: Given : Two circles with the common centre O. Three girls Reshma, Salma and Mandip are playing Class 9th Ch 10 Maths Q2 a game by standing on a circle of radius 5m drawn in a park. If the distance between Reshma and Salma and between Salma and Mandip is 6 m each, what is the distance between Reshma and Mandip? A circular park of radius 20 m is situated in a colony.

Three boys Ankur, Syed and David are sitting at equal distance on its boundary each having a toy telephone in his hands to talk each other. Find the length of the string of each phone. Let the length of each side of the equilateral triangle Class 9th Ch 10 Maths Q2 Class 9th Ch 10 Maths Q2 be 2x.

A chord of a circle is equal to the radius of the circle, find the angle subtended by the chord at a point on the minor arc and also at a point on the major arc. Solution: We Class Q2 Ch Maths 9th 10 have a circle having a chord AB equal to radius of the circle.

Solution: Class 9th Ch 10 Maths Q2 The angle subtended by an arc of a circle at its centre is Class 9th Ch 10 Maths Q2 twice the angle subtended by the same arc at a point pn the circumference. In figure, A, B and C are four points on a circle.

ABCD is Class 9th Ch 10 Maths Q2 a cyclic quadrilateral whose diagonals intersect at a point E. Solution: Since angles in the same segment of a circle are equal. If diagonals of a cyclic Class 9th Ch 10 Maths Q2 quadrilateral are diameters of the circle through the vertices of the quadrilateral, prove Class 9th Ch 10 Maths Q2 that it is a rectangle. If the non � parallel sides of a trapezium Class 9th Ch 10 Maths Q2 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 Class 9th Ch 10 Maths Q2 equal.

If circles are drawn taking two sides of a triangle as diameters, Class 9th Ch 10 Maths Q2 prove that the point of intersection of these circles lie on the third side. They Class 9th Ch 10 Maths Q2 intersect at a point D, other than A. Let us join A Class 9th Ch 10 Maths 10th Class Ncert Maths 9th Chapter Solutions Australia Q2 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 Class 9th Ch 10 Maths Q2 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 Class 10 Maths Ch 2 Solutions 9th be the radius of the circle. The lengths of two parallel chords of a circle are 6 Class Maths Ch Q2 10 9th 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 Class 9th Ch 10 Maths Q2 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 10 Maths Q2 Ch 9th Class 9th Maths Ch Q2 Class 10 of its diagonals.

Taking AB as diameter, a circle is drawn. A circle drawn Class Maths 9th Q2 Ch 10 with Q as centre, will pass through A, B and O. ABCD is a parallelogram. ABCE is a cyclic quadrilateral.

AC and BD are chords of a circle which bisect each other. Similarly, AC is a diameter. Since, opposite angles Maths Q2 10 Ch Class 9th of a parallelogram are equal. Two congruent circles intersect each other at points A and B.

Solution: We have two congruent circles such that they intersect each other at A and B. A line segment passing through A, meets the circles at P and Q. Let us draw the common chord AB. Since angles Class 9th Ch 10 Maths Q2 9th Ch Maths Class 10 Q2 subtended by equal chords in the congruent circles are equal.

The perpendicular bisector of BC passes through O. Join OB and OC. Suppose it cuts circumcirde at P. Solution: i interior ii exterior iii diameter iv semicircle v the chord vi three Ex Solution: Let us draw different pairs of circles as shown below: Class 9th Ch 10 Maths Q2 We have Figure Maximum number of common points i nil ii one �i two Thus, two circles can have at the most two points in common.
