Chapter 17: Symmetry – Complete Explanation
What is Symmetry?
Symmetry refers to a situation where one part of a figure is the mirror image of another. If a shape can be folded into two identical halves, it is said to have symmetry.
Key Concepts in Symmetry
1. Line of Symmetry
A line that divides a figure into two identical halves is called a line of symmetry.
Examples:
- A square has 4 lines of symmetry
- A rectangle has 2 lines of symmetry
- A circle has infinite lines of symmetry
2. Types of Symmetry
- Reflection Symmetry: Mirror image across a line
- Rotational Symmetry: Figure looks the same after rotation
3. Identifying Symmetrical Figures
Students learn how to:
- Draw lines of symmetry
- Identify symmetrical patterns
- Complete half-drawn figures
Why Symmetry is Important
Symmetry is widely used in:
- Art and design
- Architecture
- Nature (flowers, leaves, etc.)
Using RD Sharma Class 6 Maths Solutions for Symmetry, students can easily practice drawing and identifying symmetrical shapes.
