Jharne De and Ranjana Kumar Solutions for Chapter: Constructions, Exercise 1: Exercise

Using a ruler and a pair of compasses, construct angles of the following measures:
$30°$

Using a ruler and a pair of compasses, construct angle of the following measure:
$45°$

Using a ruler and a pair of compasses, construct angles of the following measures:
$60°$

Using a ruler and a pair of compasses, construct angles of the following measures:
$90°$

Draw an angle of $140°$with the help of a protector and bisect it using a pair of compasses.

Draw a line segment $\mathrm{A}\mathrm{B}=9\mathrm{}\mathrm{c}\mathrm{m}.$ Using a pair of compasses find the point $\mathrm{C}$ such that $\mathrm{A}\mathrm{C}=\mathrm{B}\mathrm{C}.$

Draw an angle $\mathrm{\angle }\mathrm{P}\mathrm{Q}\mathrm{R}=100°$ with the help of a protractor. Now, draw $\mathrm{\angle }\mathrm{A}\mathrm{B}\mathrm{C}=\mathrm{\angle }\mathrm{P}\mathrm{Q}\mathrm{R}$ using a ruler and a pair of compasses

Draw a line $\mathrm{A}\mathrm{B}$ and a point $\mathrm{C}$ on it. Draw a line $\mathrm{C}\mathrm{D}$ perpendicular to $\mathrm{A}\mathrm{B}.$
