# Let us fill in the blanks:

i. If the ratio of two chords PQ and RS of a circle with its centre O is 1 : 1, then ∠POQ: ∠ROS=_______________

ii. The perpendicular bisector of any chord of a circle is __________ of that circle.

Answer :

(i) 1:1

In AOB and COD

AB = CD

OA = OC = OB = OD

SSS Congruency.

So each and every angles and sides should be equal.

OAB = OCD = OBA = ODC

(ii) Passes through the origin of that Circle.

As you can see in this image The perpendicular bisector passes through the centre.

The lengths of two chords AB and CD of a circle with its centre O are equal. If ∠AOB = 60° and CD = 6 cm. then let us calculate the length of the radius of the circle.

West Bengal Board - MathematicsP is any point in a circle with its centre O. If the length of the radius is 5 cm. and OP = 3 cm., then let us determine the least of the chord passing through the point P.

West Bengal Board - MathematicsThe two circles with their centres at P and Q intersect each other at the points A and B. Through the point A, a straight line parallel to PQ intersects the two circles at the points C and D respectively. If PQ = 5 cm., then let us determine the length of CD.

West Bengal Board - MathematicsThe two circles with centers X and Y intersect each other at the points A and B. A is joined with the mid-point ‘S’ of XY and the perpendicular on SA through the point A is drawn which intersects the two circles at the points P and Q. Let us prove that PA = AQ.

West Bengal Board - MathematicsThe length of each of two parallel chord is 16 cm. If the length of the radius of the circle is 10 cm, then the distance between two chords is

West Bengal Board - MathematicsAb and CD are two equal chords of a circle with its centre O. If the distance of the chord AB from the point O is 4 cm. Then the distance of the chord from the centre O of the circle is

West Bengal Board - MathematicsThe length of a radius of a circle is 13 cm. and the length of a chord of a circle is 10 cm, the distance of the chord from the centre of the circle is

West Bengal Board - MathematicsThe lengths of two chords of a circle with centre O are equal. If ∠AOB = 60°, then the value of ∠COD is
