2023年8月3日 · What is a Circumscribed Circle. The circumscribed circle of a polygon is a circle that touches all 3 vertices of the polygon. The center of such a circle is called the circumcenter, the point where the perpendicular bisectors of the sides meet. The radius of such a circle is called the circumradius. Not every polygon though has a circumscribed ...

A circumscribed circle is a circle that passes through each point of a set of points or a polygon. Learn about the properties, examples and applications of circumscribed circles and cyclic polygons.
Circumcircle - Wikipedia
In geometry, the circumscribed circle or circumcircle of a triangle is a circle that passes through all three vertices. The center of this circle is called the circumcenter of the triangle, and its radius is called the circumradius .
