Answer»

Match the two columns;

ColumnIColumnII(A) C is a point on the minor arc AB of the circle with centre O.(p) 60 GivenACB = x. Calculatex if ACBO is a parallelogram.(B) Chord ED is parallel to the diameter AC of the circle.(q) 120 GivenCBE=55,calculateDEC.

(C) In the given figure,O is the centre of the circle.(r) 35 IfACB=60find OAB.



(D) In the given figure, O is the centre of a circle.(s) 30AOB=40 and BDC=100. Find OBC .
