- Through a point infinite number of lines can be drawn
Plot a point approximately at the centre on a sheet of paper and fold the paper in as
many ways as possible so that all the lines pass through that point. Any number of
lines can be formed and this implies that through a point infinite number of lines can
be drawn.
- Perpendicularity
Take a neatly cut paper which is in the form of a square or rectangle. Fold the paper
vertically so as to form two halves. Now fold it once again horizontally to form halves
on the other way. The impressions thus formed are perpendicular to each other.
