Final answer:
To draw a line perpendicular to a given line passing through a point, find the midpoint of the line segment and draw a line through the midpoint that is perpendicular to the given line.
Step-by-step explanation:
Step 1:
Draw a line passing through points A and B.
Step 2:
To draw a line perpendicular to AB, first find the midpoint of AB. Then, draw a line passing through the midpoint and perpendicular to AB.
Step 3:
Label the intersection point of the perpendicular line and AB as point D.
