# Diameter of a triangle's circumscribed circle (related the angles)

## Description

The circumscribed circle or circumcircle of a triangle is a circle which passes through all the vertices of the triangle. The circumcenter of a triangle can be found as the intersection of any two of the three perpendicular bisectors. (A perpendicular bisector is a line that forms a right angle with one of the triangle’s sides and intersects that side at its midpoint.). The diameter of the circumcircle of the triangle can be calculated by the area of the triangle and the sines of its angles.
