Geometry is a branch of mathematics that deals with shapes, sizes, angles, and positions of objects. It helps us understand how different shapes interact with each other in space.
Before we explore different geometrical concepts, let’s understand some basic terms:
Term |
Definition |
Example |
Point |
A location in space, represented by a dot. |
Tip of a pencil |
Line |
A straight path that extends infinitely in both directions. |
Horizon line |
Line Segment |
A part of a line with two fixed endpoints. |
Edge of a table |
Ray |
A line that starts from a point and extends infinitely in one direction. |
Sun’s rays |
Plane |
A flat surface that extends indefinitely in all directions. |
Surface of a blackboard |

Practice Questions
Identify whether the given objects represent a point, line, line segment, ray, or plane:
Edge of a notebook
A light beam from a torch
The surface of a mobile screen
Name at least three objects from your surroundings that can be classified as line segments.
Draw a ray and label its parts correctly.
Parallel Lines: Lines that never meet and remain at the same distance apart.
Example: Railway tracks.
Notation: AB || CD
Intersecting Lines: Lines that cross each other at a single point.
Example: Scissors’ blades.
Perpendicular Lines: Lines that meet at a 90-degree angle.
Example: Corners of a book.
Parallel Lines:
Intersecting Lines:
Perpendicular Lines:
Draw two parallel lines and two intersecting lines.
Give three real-life examples of parallel and perpendicular lines.
Can two intersecting lines be parallel? Explain why or why not.
Type of Angle |

Acute angle:
Right Angle:
Obtuse Angle:
Straight Angle:
Reflex Angle:
Complete Angle:
Practice Questions:
Identify the type of angles in the following:
Hands of a clock at 3:00
The top of a triangular road sign
An open book
Draw a right angle, obtuse angle, and acute angle.
Find an example of a reflex angle in real life.
Place the center of the protractor on the vertex of the angle.
Align the baseline with one arm of the angle.
Read the degree where the second arm meets the protractor scale.
Practice Questions:
Measure an angle of 45°, 90°, and 120° using a protractor.
What would be the angle formed at 6:00 on a clock?
If an angle measures 70°, is it acute, obtuse, or right?
Buildings & Architecture – Houses are built using geometrical shapes like rectangles, triangles, and circles.
Sports & Games – Football fields, basketball courts, and cricket pitches all use geometry for markings.
Nature & Environment – Honeycombs are made of hexagonal shapes.
Transport & Roads – Traffic signs are in different geometric shapes (triangles, rectangles, circles).
Technology & Design – Mobile phones and laptops have rectangular screens with curved edges.
Art & Patterns – Designs in paintings, mandalas, and mosaic art use geometric patterns.
Everyday Objects – Objects like doors, windows, clocks, and even pizza slices follow geometric properties.
