A circle is a closed plane figure, all of whose points are the same distance from a point called its center. You should know the different parts of a circle. ' A chord is a line segment with two endpoints on the circle. [DOC] [TLE] Circles [PAR] A line segment drawn from the center of the circle to a outside point of the circle is
