Class 5 Maths - KARNATAKA
Symmetrical Designs
In the chapter 'Symmetrical Designs' for Class 5 Karnataka KSEEB mathematics, students learn to identify and create balanced shapes and patterns. Symmetry is all around us in nature, art, and architecture. This chapter teaches children how to find lines of symmetry in familiar geometric shapes like squares, rectangles, circles, and triangles. Students will practice drawing lines of symmetry, completing symmetrical patterns using a grid, and creating beautiful rangoli or tile designs. Mastering this topic helps build spatial awareness, observation skills, and geometric thinking, which are essential for scoring well in board assessments and advanced geometry.

Line of Symmetry
An imaginary line that divides a shape or figure into two identical, matching halves that fit perfectly on top of each other when folded.
Symmetrical Figures
Shapes or objects that look exactly the same on both sides of a dividing line, such as a butterfly, a heart, or a square.
Asymmetrical Figures
Shapes that do not have any line of symmetry, meaning they cannot be divided into two identical halves.
Multiple Lines of Symmetry
Some special shapes have more than one line of symmetry. For example, a square has four lines of symmetry while a rectangle has two.
Completing Symmetrical Patterns
The skill of drawing the missing half of a design on a grid by mirroring the exact dots and lines across the line of symmetry.

Board Exam Info
In the Karnataka (KSEEB) Class 5 Mathematics examinations, this chapter typically carries about 4 to 6 marks. Common question types include drawing lines of symmetry for given geometric shapes, identifying whether a shape is symmetrical or asymmetrical, and completing the other half of a drawing using a dotted line of symmetry on a grid.
Frequently Asked Questions
What is a line of symmetry?
A line of symmetry is a straight line that splits a figure into two identical parts that are mirror images of each other.
Do all shapes have a line of symmetry?
No, some shapes are asymmetrical and do not have any lines of symmetry, while other shapes can have one, two, or many lines of symmetry.
How many lines of symmetry does a circle have?
A circle has an infinite number of lines of symmetry because any line passing through its center will divide it into two identical halves.
