The radius of the circumcircle of a triangle with sides cm, cm and cm is found by—
- aconstructing the perpendicular bisectors of two sides and measuring the distance from their intersection to a vertex
- bconstructing angle bisectors
- cdrawing the altitudes
- ddrawing the medians

The circumcentre is found where the perpendicular bisectors of the sides meet, since it is equidistant from the vertices. Measuring from that intersection to any vertex gives the circumradius directly.
