The center of this circle is called the circumcenter and its radius is called the circumradius. An incircle or inscribed circle of a triangle is the largest circle contained in the triangle; it touches (is tangent to) the three sides.The center of the incircle is called the triangle’s incenter and its radius is called inradius.
