Q2 Does Euclid’s fifth postulate imply the existence of parallel lines? Explain.
According to Euclid's 5 postulates, the line PQ falls on lines AB and CD such that the sum of the interior angles 1 and 2 is less than 180° on the left side of PQ. Therefore, the lines AB and CD will eventually intersect on the left side of PQ
Now,
If then, the line never intersects with each other.
Therefore, we can say that lines AB and CD are parallel to each other
