R K Bansal Solutions for Chapter: The Circle, Exercise 1: EXERCISE

Draw a circle of radius $6 \mathrm{cm}$. In the circle, draw a chord $AB=6 \mathrm{cm}$.

If $O$ is the centre of the circle, join $OA$ and $OB$.

Draw a circle of radius $6 \mathrm{cm}$. In the circle, draw a chord $AB=6 \mathrm{cm}$.

Assign a special name to $∆AOB$

Draw a circle of radius $6 \mathrm{cm}$. In the circle, draw a chord $AB=6 \mathrm{cm}$.

Write the measure of angle $AOB$.

Draw a circle of radius $4.8 \mathrm{cm}$ and mark its centre as $P$.

Draw radii $PA$ and $PB$ such that $\angle APB=45°$.

Draw a circle of radius $4.8 \mathrm{cm}$ and mark its centre as $P$.

Shade the major sector of the circle,

Draw a circle of radius $3.6 \mathrm{cm}$. In the circle, draw a chord $AB=5 \mathrm{cm}$. Now shade the minor segment of the circle.

Mark two points $A$ and $B$, $4 \mathrm{cm}$ apart.

Draw a circle passing through $B$ and with $A$ as centre.

Draw a line $AB=8.4 \mathrm{cm}$. Now draw a circle with $AB$ as diameter.

Mark a point $C$ on the circumference of the circle. Measure angle $ACB$.
