Draw two circles of the same radii. $A$ is the centre of one circle and $B$ is the centre of the other circle. Draw one of the circles in such a way that it passes through the centre of the other.

Draw a line segment of length $3.5 \mathrm{cm}$. Mark a point $A$ on it. Construct a perpendicular to the line segment passing through point $A$.

Count the number of circles in the figure.

Draw an angle Of ${70}^o$ with a protractor and bisect it by using a pair of compasses.

Draw a line $PQ=5 \mathrm{cm}$ and take a point $A$ on it such that $AP=3 \mathrm{cm}$. Taking $A$ as the centre, draw an angle of ${90}^o$ using a compass.

Draw any line segment $AB$ and take a point $P$ outside it. Construct a perpendicular on $AB$ passing through $P$.
