Dynamic Geometry: Circumcenter,
Circumcircle
The interactive figure above, created with GeoGebra,
shows a triangle ABC with the perpendicular bisectors intersecting at
a point O, called circumcenter. The circumcenter is the center of the
circumscribed circle or circumcircle The circumradius is the radius of
the circumcircle..
