Abstract :

I'll give a brief introduction of Hyperbolic Geometry. I would also visit a journey of non-Euclidean Geometry which was discovered from the 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 extended indefinitely, meet on the side on which the angles are less than two right angles." (Euclid's fifth postulate) No prerequisites are required.
