The vertices of a triangle are `O(0,0),\ A(a ,0)a n d\ B(0, b)` . Write the coordinates of its circumcentre.

Explanation

The coordinates of circumcentre of a triangle are the intersection of perpendicular bisectors of any sides of the triangle.

Thus, the coordinates of circumcetre of triangle are `(frac{a}{2}, frac{b}{2}).`
