How to Calculate the Inradius and Circumradius The inradius is the radius of the inscribed circle, which is a circle that is tangent to all three sides of the triangle. In other words, it is the largest circle that can fit inside the triangle. ...
• Inscribed Circle Radius a × Sin(C/2) × Sin(B/2) / Cos (A/2) or b × Sin(A/2) × Sin(C/2) / Cos (B/2) or c × Sin(A/2) × Sin(B/2) / Cos (C/2)Triangle Types All three angles of a triangle always add up to 180 ̊C. Triangle has three types based...
