Introduction To Euclid’s Geometry

Euclid’s fifth postulate is
(A) The whole is greater than the part.
(B) A circle may be described with any centre and any radius.
(C) All right angles are equal to one another.
(D) 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 angles, then the two straight lines if
produced indefinitely, meet on that side on which the sum of angles is less than two
right angles.
