Question

Draw a line segment $AB=5\mathrm{cm}$. Take a point $Q$ on $AB$. Draw $\perp$on $AB$ using set-squares.

Answer 1

Perpendicular Lines and Perpendicular Bisector

Step $1.$ Drawing a line segment and constructing perpendicular on it using set-squares through a point lying on it

Draw a line segment $AB=5\mathrm{cm}$. Take a point $Q$ on it. Set an edge of the set-squares containing the angle of ${90}^o$ on the given line segment $AB$ so that the other edge is just in contact with the point $Q$.

Draw a line that passes through the given point $P$ and produce it to $P$ with the help of the set-square.

Thus, $PQ\perp AB$
