WebSep 15, 2024 · For any triangle ABC, the radius R of its circumscribed circle is given by: 2R = a sinA = b sin B = c sin C Note: For a circle of diameter 1, this means a = sin A, b = sinB, and c = sinC .) To prove this, let O be the center of the circumscribed circle for a triangle ABC. WebPlane Geometry Practice Workbook with Answers - Jan 06 2024 Learn and practice essential geometry skills.
