This is a free lesson from our course in Geometry A circle is an important shape in the field of geometry. In this lesson you�ll explore further to the earlier learning about circle. Starting from definition and parts of the circle, it explains the relationship between the circle, circle parts and the plane. Circle: A circle is the set of all points in a plane that are equidistant from a fixed point of the plane called the center of the circle. If the center of a circle is point O, the circle is called circle O, written in symbols as O. E.g. in real word- a cycle wheel, circular dinner plate etc. Further you�ll learn more about the relationship of its parts and the plane. This section also covers on equation of circle, arcs, chords, tangents, sector, segment, secant etc & inscribed and Circumscribed Polygons etc. with watch video and explanation by the instructor in own hand writing with the help of several examples.
