NCERT Solutions Chapter 11: Constructions

In earlier chapters, the diagrams, which were necessary to prove a theorem or solving excercise were not necessarily precise. They were drawn only to give you a feeling for the situation and as an aid for proper reasoning. However, sometimes one needs an accurate figure, for example - to draw a map of a building to be constructed, to design tools, and various parts of a machine, to draw road maps etc. To draw such figures some basic geometrical instruments are needed. You must be having a geometry box which contains the following:
(i) A gradusted scale, on one side of which centimetres and millimetres are marked off and on the other side inches and their parts are marked off.
(ii) A pair of set - squares, one with angles {tex}90^\circ ,\,60^\circ \,and\,30^\circ {/tex} and other with angles {tex}90^\circ ,\,45^\circ \,and\,45^\circ . {/tex}.
(iii) A pair of dividers (or a divider) with adjustments.
(iv) A pair of compasses (or a compass) with provision of fitting a pencil at one end.
(v) A protractor.
