Q16 of 31 Page 65

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.

(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.

AB and AC are two equal chords of a circle having the radius of 5 cm. The centre of the circle

is situated at the outside of the triangle ABC. If AB = AC = 6 cm. then let us calculate the length of the chord BC.
