How many parallel lines can be be drawn through a point not on the given line?

We know, that through a given point we can draw infinite number of lines, but only one of those infinite line will be parallel to the given line.

This is known as the parallel postulate of Euclidean geometry, which states that given a line and a point not on the line, there is exactly one line that passes through the point and is parallel to the given line. This is one of the fundamental axioms of Euclidean geometry, and it has important implications for the properties of parallel lines and angles.
