Jharne De Solutions for Chapter: Constructions, Exercise 1: Exercise

Using a scale and a pair of compasses, draw the line segments of the following lengths.

$4.5 \mathrm{cm}$

Using a scale and a pair of compasse, draw the line segment of the following length.

$6.2 \mathrm{cm}$

Draw two line segments $AB$ and $CD$ of lengths $2.5 \mathrm{cm}$ and $6.3 \mathrm{cm}$, respectively. Construct the line segments of the following lengths.

$AB+CD$

Draw two line segments $AB$ and $CD$ of lengths $2.5 \mathrm{cm}$ and $6.3 \mathrm{cm}$, respectively. Construct the line segments of the following lengths.

$CD+AB$

Draw a line segment of $6 \mathrm{cm}$. Draw a perpendicular to the line segment from point $P$ lying outside the line segment.

Draw a circle of radius $4.2 \mathrm{cm}$ with the centre at $O$. Mark three points $A, B,$ and $C,$ such that point $A$ is on the circle, $B$ is in the interior, and $C$ is in the exterior of the circle.

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 $A$.
