R. D. Sharma Solutions for Chapter: Constructions, Exercise 1: EXERCISE

Draw an $\angle BAC$ of measure $50°$ such that $AB=5 \mathrm{cm}$ and $AC=7 \mathrm{cm}$. Through $C$ draw a line parallel to $AB$ and through $B$ draw a line parallel to $AC$, intersecting each other at $D$. Measure $BD$ and $CD$.

Draw a line $PQ$. Draw another line parallel to $PQ$ at a distance of $3 \mathrm{cm}$ from it.

Take any three non-collinear points $A, B, C$ and draw $△ABC$. Through each vertex of the triangle, draw a line parallel to the opposite side.

Draw two parallel lines at a distance $5 \mathrm{cm}$ apart.
