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`.

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

In the given figure, AB is the diameter of the circle. Find the value of angleACD :

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

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=
