This shape is generated in polar coordinates by setting the value of r equal to a constant.
Two similar triangles are drawn inside one of these shapes in the Butterfly Theorem. An angle whose rays both intersect this shape twice is subject to the Secant-Secant Theorem, and the power of a point depends on its location relative to the center of one of these shapes. This shape is generated in polar coordinates by setting the value of r equal to a constant. Name this locus [LOE-kus] of all points in a plane a fixed distance from a fixed point, a shape whose area can be found by multiplying pi times radius squared.
