 Parallel Postulate: if there is a line and a point not on the line, then there is exactly one line through the point parallel to the given line.

 Perpendicular Postulate: if there is a line and a point not on the line, then there is exactly one line through the point perpendicular to the given line. "'':" :

 Transversal: A line that intersects two or more lines at different points. Spot the transversal!
