(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. Derivation: If you have some questions about the angle θ shown in the figure above, see the relationship between inscribed and central angles. The formula for the radius of the circle circumscribed about a triangle ( circumcircle) is given by. The circumscribed circle is the circle drawn outside of any other shapes such as polygon, touching all the vertices of the polygon, and is termed as circumcircle. We let , , , , and .We know that is a right angle because is the diameter. The radius of circumscribed circle represents the length of any line segment from its center to its perimeter, of the circumscribed circle and is represented as r c = (S a * S b * S c)/(4* A) or circumradius = (Side A * Side B * Side C)/(4* Area).Side A is an upright or sloping surface of a structure or object that is not the top or bottom and generally not the front or back, Side B is an .
