Circle: A planar figure that consists of points that are the same distance (the radius) from a fixed point (the center). Equilateral triangle inscribed in a circle: This occurs when the vertices of the equilateral triangle are on the circle. By symmetry, the center of the equilateral triangl...
The inscribed circle radius is required to be 1 unit. The three escribed circles that have equal radii must have 3 units each, and the circumcircle of the triangle must have 2 units. All these requirements may seem outlandish. The aim is to teach crucial Geometric principles that Geometric ...
