Draw a circle of radius $3.2$ $\mathrm{cm}$ and in it make a sector of angle.

$2\frac{2}{3}$ right angles

Shade the sector.

A line meets a circle at most in _____ points. ($0/1/2/$Infinite)

One-half of the whole arc of a circle is called a _____.

The angle subtended by an arc of a circle at the centre of the circle is called the _____ subtended by the arc. (angle / arc)

A line which meets a circle in one and only one point is called a _____ to the circle.

The tangent at any point of a circle and the radius through that point are _____ to each other. $\left(\mathrm{perpendicular} / \mathrm{parallel}\right)$

In the adjoining figure, the tangent to a circle of radius $6 \mathrm{cm}$ from an external point $P$ is of length $8 \mathrm{cm}$. Calculate the distance of the point $P$ from the nearest point of the circumference.

In the given figure, $O$ is the centre of the circle. If $\angle ABP=35°$ and $\angle BAQ=65°$, find $\angle PAB$.

In the given figure, 0 is the centre of the circle. If $\angle ABP=35°$ and $\angle BAQ=65°$, find$\angle QBA$
