Constructing a perpendicular from a point to a lin

Open compass so its bigger than distance from point (P) to the line

Draw to arcs (A) (B) on the line

Draw two crossing arcs below the line (C)

Draw a line joining P to C

Constructing the perpendicular from a point on a l

Set compass to any length

Draw 2 arcs on the line (A) (B)

Keep the compass same length and draw 2 crossing arcs above and below the line

Draw a line connecting the 2 arcs and the point
