The circle has fascinated mathematicians since ancient times. This
entertaining book describes in layperson's terms the many intriguing
properties of this fundamental shape. If math has intimidated you, this
may be the ideal book to help you appreciate the discipline through one
of its most important elements. The authors begin with a brief review of
the basic properties of the circle and related figures. They then show
the many ways in which the circle manifests itself in the field of
geometry--leading to some amazing relationships and truly important
geometric theorems. In addition, they explore remarkable circle
constructions and demonstrate how all constructions in geometry that
usually require an unmarked straightedge and a compass can also be done
with the compass alone. Among other things, the reader will learn that
circles can generate some unusual curves - many even quite artistic.
Finally, the role of circles in art and architecture and a discussion of
the circle's place on the sphere bring full circle this presentation of
a key element of geometry.
