CBSE 9th Maths | Chapter 5 | Euclid's Geometry | Introduction | In tamil

Euclidean geometry is an example of synthetic geometry, in that it proceeds logically from axioms describing basic properties of geometric objects such as points and lines, to propositions about those objects, all without the use of coordinates to specify those objects. The Greek mathematicians of Euclid’s time thought of geometry as an abstract model of the world in which they lived. The notions of point, line, plane (or surface), and so on were derived from what was seen around them. From studies of the space and solids in the space around them, an abstract geometrical notion of a solid object was developed. A solid has shape, size, position, and can be moved from one place to another. Its boundaries are called surfaces. They separate one part of the space from another and are said to have no thickness. The boundaries of the surfaces are curved or straight lines. These lines end in points. Starting with his definitions, Euclid assumed certain properties, which were not to be proved. These assumptions are actually ‘obvious universal truths’. He divided them into two types: axioms and postulates. He used the term ‘postulate’ for the assumptions that were specific to geometry. Common notions (often called axioms), on the other hand, were assumptions used throughout mathematics and not specifically linked to geometry. For details about axioms and postulates are explained in this video. Hi, students and teachers here I explained about Pair of linear equations in two variables. Here the equations come as pair or we have to make the application sums into the equation. Before going to that process here the introduction of the topic which we gonna look upon. So three types of graphs and three types of methods to solving the pair of linear equations will be handled further. Moreover, this topic has more exercises so with some patients we go through this chapter and don't skip any videos and don't skip any sums. Here is the link for the playlist on Pair of linear equations: https://www.youtube.com/playlist?list... Here is the link for the playlist on Polynomials https://www.youtube.com/playlist?list...
