# What does "Foot" mean in Vectors in C4 - AQA Watch

1. example:

Hence find the coordinates of the foot of the perpendicular from the point A to the line l.

What does 'foot' mean?

Thanks
2. The foot is where the perpendicular line from point A meets the line l.

The foot is where the perpendicular line from point A meets the line l.
Still confused.

The foot of the perpendicular is a point (not a line), and I'm not sure your diagram is right anyway.

Draw a point A and a line l (not going through A). Then draw a line from A which intersects the line l and is perpendicular to it. Call the point of intersection F. Then F is the foot of the perpendicular. For example, in your diagram, B is the foot of the perpendicular from A to the line BP, and is also the foot of the perpendicular from P to the line AB.
