The equation of a circle is based upon its definition and the Pythagorean theorem. Since a locus for the circle is “the set of points equidistant from a single point called the center” and that distance between the center and the point on the circle is a constant radius, then we can consider the radius to be the hypotenuse of all right triangles whose sides are the differences between the
