Construction (works whether P is on m or not):

1. With compass centered at P draw an arc that meets line m in two points A and B. (If P lies on m, choose any radius so the arc cuts m on both sides of P.)
2. With the compass set to any radius greater than half of AB, draw arcs centered at A and B above and below line m so that the two pairs of arcs meet. Let the intersection points of the arcs be C and D.
3. Draw the line through C and D. That line is the perpendicular bisector of AB, hence it passes through P (PA = PB) and is perpendicular to m.

Reason: P is equidistant from A and B, so P lies on the perpendicular bisector of AB; the perpendicular bisector is perpendicular to AB (and to m), so CD is the required perpendicular through P.
