Answer»

Match the two columns;



Column-IColumn-II(A) C is a point on the minor arc AB of the circle with centre O.(P) 60∘ Given∠ACB = x. Calculate ∠x if ACBO is a parallelogram.(B) Chord ED is parallel to the diameter AC of the circle.(q) 120∘ Given∠CBE = 55∘, calculate∠DEC.



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







(D) In the given figure, O is the centre of a circle.(s) 30∘∠AOB = 400 and ∠BDC = 1000. Find ∠OBC .
