## Ncert Solutions For Class 9 Maths Chapter 5 Ex 5.2

Question 1:

Write a way in which Euclid’s fifth postulate could be more understandable.

Euclid’s fifth postulates are about parallel lines.

Parallel lines are lines in which never intersect each other and are always at a perpendicular distance between them which is constant distance. Parallel lines can be two or more lines.

A: If X does not lie on the line A then we can draw a line through X which will be parallel to that of the line A.

B: There can be only one line that can be drawn through the point X which is parallel to the line A.

Question 2:

Does Euclid’s fifth postulate imply for the existence of parallel lines? Explain.

1+3=180$\angle 1+\angle 3=180^{\circ}$
Or 3+4=180$\angle 3+\angle 4=180^{\circ}$
