If a straight line falling on two straight linesmakes 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.
It is a consequence of Euclids's parallel postulate.
No.

Could you please specify which postulate you are referring to?

need a simple explanation of Euclids theory.
Because it will eventually complete a Circle, like the dachshund that met its end going round a lamp-post.

Euclidean geometry is the study of points, lines, planes, and other geometric figures. The most prolonged argument over time has been that of the parallel postulate which states: there can only be one line that contains a given point and is parallel to another line.

Yes by one definition of interior angles - it does !
