Overview
Geometry is the study of shapes, sizes, and positions of objects in space. The word 'Geometry' comes from Greek words 'Geo' (Earth) and 'metron' (Measurement). In this chapter, you will learn the fundamental building blocks of geometry - points, lines, rays, angles, and polygons. These concepts form
Key Concepts
A point is the most basic
A point is the most basic unit in geometry. It is represented by a tiny dot made by a sharp pencil tip. A point has no length, width, or height - it o
A line segment is the shortest
A line segment is the shortest distance between two points. It has two endpoints and a fixed length. When you fold a piece of paper and see the crease
