Question

Draw a line AB and draw another line CD parallel to AB at a distance of 3.5 cm from it.

Answer 1

$\begin{array}{l}\text{Steps for construction:}\\ 1.\text{Let AB be the given line}\text{.}\\ 2.\text{Take any two points P and Q on AB}\text{.}\\ \text{3}\text{. Construct}\angle BPE=90°\text{and}\angle BQF=90°\\ 4.\text{With P as the centre and the radius equal to 3}\text{.5 cm, cut PE at R.}\\ \text{5}\text{. With Q as the centre and the radius equal to 3}\text{.5cm, cut QF at S.}\\ \text{6}\text{. Join RS and produce it on both the sides to get the required line, parallel to AB and at a distance of 3}\text{.5 cm from it}\text{.}\\ \\ \end{array}$
