Constructions

11.1 Introduction

We have learnt some of constructions using a straight edge (ruler) and a compass, e.g., bisecting an angle, drawing the perpendicular bisector of a line segment, some constructions of triangles etc. and also gave their justifications.

Here we will learn some more constructions by using the knowledge of the earlier constructions.

11.2 Division of a Line Segment

To divide a line segment in a given ratio.

The same methods would apply for the general case also.

11.3 Construction of Tangents to a Circle

To construct the tangents to a circle from a point outside it.
