ways to prepare the chapter circles

important points

   Circle: It is a collection of all points in a plane which are at a constant distance from a fixed point. The fixed point is called the centre and the constant distance is called the radius.

   Chord: Any line segment joining two points on the circle is called a chord. The chord passing through the centre of the circle is called the diameter.

   Secant: A line intersecting the circle in two points is called a secant.

   Tangent: A line that intersects the circle at only one point.

   Theorem 1: The tangent to any point of a circle is perpendicular to the radius through the point of contact.

   Theorem 2: The lengths of tangents drawn from an external point to a circle are equal.
