Maths 1 Marks Question

The common point of a tangent and the circle is called point of contact. In fig AB is tangent line P is point of contact between circles and tangent line.

The angle between tangent at a point on a circle and the radius through the point is 90°.
In fig, AB is tengent line P is point of contact O. P is radius. So, angle between OP and AB is 90°.

A tangent to a circle intersects in it one point(s).
In fig AB is tengent line.
P is point of contact between circle and tangent line.

A line intersecting a circle in two points is called a Secant.
In fig AB is secant. AB intersect a circle in 2 point P and Q.
