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.
