Question

Draw a line segment of length 6 cm. From a point P outside the line, draw a perpendicular on this line.

Answer 1

Steps of construction:
1. First of all draw a line segment $AB=6cm$
2. Take a point P (outside the line) and draw an arc in such a way that it cuts $AB$ into two points $C$ and $D.$ Again by taking $C$ & $D$ as centre take suitable arc and draw two arc which intersect at $Q$. Join $PQ.$
Hence, $PQ$ is the required perpendicular on $AB$ from $P.$
