West Bengal Board Solutions for Chapter: Drawing of Different Geometrical Figures, Exercise 3: Lets work out-22.2

Draw a line segment $AB$ of length $5 cm$ with scale and pencil. By folding paper, find the perpendicular bisector of the line segment $AB$. Then measure the two bisected parts with scale.

Draw a line segment of length $8 cm$ with scale and pencil. Then draw a perpendicular bisector of this line segment and measure each part.

Draw a line segment $PQ$ of length $6 cm$. With scale and pencil, take line segment $PQ$ as diameter and draw a circle.

With the help of scale and pencil a line segment $AB$ of length $8 cm$ is drawn. Divide the line segment $AB$ into four equal parts and measure each part.

Draw two circles whose diameters are $5 cm$ and $7 cm$ respectively.

Masum draw a triangle $\text{ABC}$. Then with the help of scale and pencil, compass, she bisected the sides $\mathrm{BC}, \mathrm{AC}, \mathrm{AB}$ perpendicularly. She verified, if perpendicular bisectors are concurrent. If concurrent, she named it $O$. Now with centre $O$ and radius equal to line segment $AO$, she drew a circle.
