Euclid’s fifth postulate is
1
The whole is greater than the part.
2
A circle may be described with any central and any radius.
3
All right anlges are equal to one another.
4
If a straight line falling on two straight lines makes the interior angles on the same side of it taken together less than two right anlges, then the two straight lines if produced indefinitely, meet on that side on which the sum of the angles is less than two right anlges.
