The circumcircle of a triangle is the unique circle determined by the three vertices of the triangle. ... The incircle of a triangle is the circle inscribed in the triangle. Its center is called the incenter (green point) and is the point where the (green) bisectors of the angles of ...
When a circle and a triangle are together, there is such a thing as the radius of a triangle. What is the radius of a triangle? There are two types of radii for triangles: inradius: This is the radius of a circle inscribed in a triangle. circumradius: This is the radius of the ...
The formula for the radius of the circle circumscribed about a triangle (circumcircle) is given by R=abc4AtR=abc4At where Atis the area of the inscribed triangle. Derivation: If you have some questions about the angle θ shown in the figure above, see therelationship between inscribed and ce...

Cramer-Castillon on a Triangle's Incircle and Excircles The Cramer-Castillon problem (CCP) consists in finding one or more polygons inscribed in a circle such that their sides pass cyclically through a list of N N points. We study this problem where the points are the vertices of a trian...
Hence, we have proven that for this case, where the diameter of circle Q is one of the chords forming the inscribed angle ∠DRU, the measure of the central angle is twice the measure of the inscribed angle θ. Case 2: When the diameter is in the interior of the inscribed angle ...
