Chapter Summary

--- PAGE 1 --- 2 LINES AND ANGLES 0674CH02 In this chapter, we will explore some of the most basic ideas of geometry including points, lines, rays, line segments and angles. These ideas form the building blocks of 'plane geometry', and will help us in understanding more advanced topics in geometry such as the construction and analysis of different shapes. 2.1 Point Mark a dot on the paper with a sharp tip of a pencil. The sharper the tip, the thinner will be the dot. This tiny dot will give you an idea of a point. A point determines a precise location, but it has no length, breadth or height. Some models for a point are given below. The tip of a compass The sharpened end of a pencil The pointed end of a needle If you mark three points on a piece of paper, you may be required to distinguish these three points. For this purpose, each of the three points may be denoted by a single capital letter such as Z P T Reprint 2025-26 --- PAGE 2 --- Ganita Prakash | Grade 6 Z, P and T…
