Question

Draw a figure roughly like one shown, but larger. Do the indicated construction clearly enough so that your method can be understood easily.

The perpendicular to $\overleftrightarrow{BA}$ at $A$.

Short answer

Step-by-step solution

Step 1. Given information.   

Step 2. Concept used.

Draw with the help of compass.

Step 3. Construction.

Step 1: Measure the distance between the points$A and B$ and copy that distance through extended line $AB$ such that$AB=AM$.

Step 2: Draw similar arcs from $M and B$ from both the sides of line $MB$.

Step 3: Mark intersections of these arcs $P and Q$.

Step 4: Join $PQ$. This will be the required line.
