Answer
Draw a line $AB$ and take two points $C$ and $E$ on the opposite sides of the line $AB.$ On the side of $E,$ place a set-square $PQR,$ such that its one arm $PQ$ of the right angle is along the line $AB.$ Without disturbing the position of the set-square, place a ruler along its edge $PR.$ Now, without disturbing the position of the ruler, slide the set square along the ruler until the arm $QR$ reaches point $C.$ Without disturbing the position of the set-square, draw a line $CD$, where $D$ is a point on $AB. CD$ is the required line and $\text{CD}\perp\text{AB}.$ We repeat the same process starting with taking set-square on the side of $E,$ we draw a line $\text{EF}\perp\text{AB}.$
