## NCERT Solutions for Class 9 Maths Chapter 5 Introduction to Euclid’s Geometry Exercise 5.2

Question 1.

How would you rewrite Euclid’s filth postulate so that it would be easier to understand?

Solution:

Two lines are said to be parallel if they are equidistant from one other and they do not have any point of intersection. eg.

Question 2.

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

Solution:

Yes,

According to Euclid’s 5th postulate when n line falls on 1 and m and if ∠1 + ∠2 < 180° and ∠3 + ∠4 > 180° and then producing line l & m further will meet in the side of ∠1 and ∠2 which is less than 180°. Which gave the clue about the condition when ∠1 + ∠2 = 180° and the line l and m will not meet at any point.
