The radius of a circle is 8 cm and O is its centre. If angle AOB=60^(@) and AB is a chord, then what is the length of the chord AB?

O is the centre of a circle of diameter AB. If chord AC= chord BC, then find the value of angleABC .

O is the centre of a circle of diameter AB. If chord AC= chord BC, then find the value of angleABC .

In the following figure AB=21cm, BC=15 cm, AC=24 cm. Point P is the mid-point of arc AC, and chord BD bisect chord AC at P. find the ratio BP/PD.

In Fig. 2.47, O is the centre of the circle. Name all chords of the circle.

In the above figure, O is the centre of the circle AB,AD and CD are the chords . If /_ ADC=130^(@) then fid /_ ACB .

In the figure, diameter AB and chord CD intersect in point E. If m (arc CXB ) = 100^(@) . Find (i) /_ADC (ii) /_CDB (iii) /_ ACB

In the figure, m ( arc PAQ ) =m (arc RBS ) =130^(@) chord PQ has length 10cm then what is the length of chord RS ? Why ?
