Find the distance between two parallel tangents of a circle of radius $8 \mathrm{cm}$.

$PQ$ and $PT$ are tangents to a circle with centre $O$ and radius $5 \mathrm{cm}$. If $PQ=12 \mathrm{cm}$, then prove that the perimeter of the quadrilateral $PQOT$ is $34 \mathrm{cm}$.

A tangent to a circle is perpendicular to the radius through the point of contact.

Define radius of a circle.

A line which intersects a circle in two distinct points is called the _____ of the circle.

In the adjoining figure, $PS$ and $PT$ are tangents to the circle drawn from an external point $P$. $CD$ is a third tangent touching the circle at $Q$. If $PT=10 \mathrm{cm}$ and $CQ=2 \mathrm{cm}$, find the perimeter of $∆PCD$.

Prove that the lengths of tangents drawn from an external point to a circle are equal.

Define a tangent to a circle.
