Color diagram showing Euclid's postulate. A line labeled "L" is shown with a thick, dark blue line. The background is a light gray-blue grid. A red point labeled "P" sits below (not on) L, and a thick red line is drawn through P that is parallel to L. A second violet line passes through P at a different angle and therefore intersects L.

In Euclid's geometry, if you have a line L and a point P that is not on L, then there is exactly one line through P that does not intersect L. That line is parallel to L.
