In figure, AOB is a diameter of the circle and C, D, E are any three points on the semi-circle. Find the value of angleACD+ angleBED .

AB is a diameter of a circle and C is any point on the circumference of the circle, then :

AB is a diameter of a circle and 'C' is any point on the circumference of the circle .Then

AOB is a diameter of a circle , C is a point on the circle. If angle OBC=60^(@) , then find the value of angleOCA

If AOB is a diameter of a circle and C is a point on the circle, then AC^(2)+BC^(2)=AB^(2) .

If AOB is a diameter of a circle and C is a point on the circle, then AC^(2)+BC^(2)=AB^(2) .

AB is a diameter of a circle. C is any point on the circle, angleACB=

In Fig. 10.32, AB is a diameter of the circle, CD is a chord equal to the radius of the circle. AC and BD when extended intersect at a point E. Prove that angle AEB = 60^@ .
