Introduction
Geometry is the study of shapes, lines, and angles all around us. From the edges of your notebook to the corners of your classroom, geometric ideas help us describe and understand the world. These notes will guide you through basic terms and ideas with simple definitions and fun examples.

Fundamental Geometrical Concepts
| Concept | Definition | Diagram |
| Point | A point is a mark of position. It has neither length nor width nor thickness. |  |
| Line | A line has only length. It has neither width nor thickness. |  |
| Line Segment | A line segment is a part of a straight line. |  |
| Ray | A ray is a straight line that starts from a given fixed point and moves in a same direction. |
 |
| Plane | It is a flat surface. A plane has length and width but no thickness. |  |
| Angle | It is formed when two rays meet at a common point (vertex). |  |
