Question

Given an arc of the circle. complete the circle​

Answer 1

Let PQ^be an arc of the circle.

In Order to complete the circle we have to find its Center and radius .

Take a point R on the are

PQ^and join PR and QR . Draw perpendicular bisector of PR and RQ respectively . Let these perpendicular Bisector intersect bisector at point O .

Then , OP=OQ . Draw a circle with centre O and radius =OP=OQ to get the required circle .
