A circumcircle is a circle that touches the three vertices of a circle from outside.
It can easily be constructed by the following steps:
- Construct the perpendicular bisectors of each side of the triangle
- Locate the point of intersection of the bisectors
- The point of intersection is the centre of the circumcircle
- Construct the circle with centre in step 3). It is the circumcircle of the triangle in question.
