Chords AB andCD of a circle with centre O are congruent. If m(arc AXB) `= 120^(@)` then what is the m(arc( CYD).

Chords AB and CD of a circle intersect in point Q in interior of a circle. If m(arc AD)= 25^(@) and m(arc BC)= 31^(@) , find /_BQC .

A circle with centre 'O' . Chord PQ~= chord RS . M(arc PXQ) =260^(@) . Then find m (arc RXS).

A circle with centre 'O', chord PQ ~= chord RS. m(arc PXQ)=260^@ . Then find m(arc RXS)

If arcs AXB and CYD of a circle are congruent, find the ratio of AB and CD.

If arc AXB and CYD of a circle are congruent, find the ratio of AB and CD
