Circle

Circles of Class 10

A circle is the locus of a point which moves in a plane in such a way that its distance from a fixed point remains constant.

SECANT:

A line, which intersects a circle in two distinct points, is called a secant.

Circle

TANGENT:

A line meeting a circle only in one point is called a tangent to the circle at that point.

The point at which the tangent line meets the circle is called the point of contact.

LENGTH OF TANGENT:

The length of the line segment of the tangent between a given point and the given point of contact with the circle is called the length of the tangent from the point to the circle.

Circle

  • There is no tangent passing through a point lying inside the circle.
  • There is one and only one tangent passing through a point lying on a circle.
  • There are exactly two tangents through a point lying outside a circle.
