**Question**: **Define the term line segment. Are there other terms that need to be defined first? What are they, and how might you define them?****Answer**: The other terms which need to be defined first before defining line segment are line and point.

Line- A line is a straight one-dimensional figure having no thickness and extending infinitely in both

directions.

Point- A point in geometry is a location. It has no size i.e. no width, no length and no depth. A point is shown by a dot. Line segment- The part of a line that connects two points or it can also be defined as a line with two end points. Example of line segment is given below.

**Question**: Why is Axiom 5, in the list of Euclid’s axioms, considered a ‘universal truth’? (Note that the question is not about the fifth postulate.)**Answer**: Axiom 5: The whole is greater than the part.

Let Z be the whole.

Z=A+B+C We can see A, B and C are part of Z. Clearly, Z will be greater than all its parts A,B and C. This axiom is known as a universal truth because it holds true in any field, and not just in the field of mathematics

We have used the knowledge of Trignometry to build pyramids, houses, statutes, drainage systems and many more constructions. Euclid is also known as the father of geometry. He has constructed many theorems and formulas that are very helpful when it comes to solving difficult geometry problems.

Euclid also defined a point, line, straight line, surface, plane surface. In this chapter you will be studying Axioms, and Postulates. Postulates. The Postulates are the assumptions that are specific to geometry. While the axioms are the assumptions not specific to the geometry.

Now that we have provided you with the NCERT Solutions for Class 9 Maths Chapter 5. We expect you to use these solutions at your best and solve all the NCERT Questions present in the textbook. The more you solve, the better your problem-solving ability will become. Eventually, you will be able to perform well in the final exam.
