Attempts to prove Euclid’s fifth postulate using other postulates and axioms led to the discovery of several other geometries.

Euclid’s fifth postulate: if a straight line falling on two straight lines makes the interior angles on the same side less than two right angles, the two straight lines if produced indefinitely, meet on that side on which the angles are less than two right angles.

It means that if the sum of angles ÐA and ÐB in the figure is less than the sum of two right angles then A, and B meet on the same side of angles A and B continue indefinitely.

All attempts to prove the fifth postulate as a theorem led to great achievement in the creation of several other geometries. These geometries are different from Euclidean geometry and are called non-Euclidean geometry.
