If a line segment intersects two straight lines forming two interior angles on the same side that sum to less than two right angles, then the two lines, if extended indefinitely, meet on that side on which the angles sum to less than two right angles.

If the sum of the interior angles α and β is less than 180°, the two straight lines, produced indefinitely, meet on that side.
