Symmetry

What is Symmetry?

  • Symmetry means both sides are the same.
  • A shape is symmetrical if it can be folded into two equal halves.

✂️ Line of Symmetry

  • The line that divides a shape into two equal parts is called a line of symmetry.
  • When you fold along this line, both sides match exactly.

👀 Examples of Symmetry

  • 🦋 Butterfly
  • ❤️ Heart
  • 🔲 Square
  • 🍃 Leaf

👉 These all have equal left and right sides.

❌ Not Symmetrical Shapes

  • Shapes that do not match when folded are not symmetrical.
  • Example: uneven or irregular shapes.

🎯 Easy Tips for Students

  • Fold the shape → Do both sides match?
  • If YES ✅ → Symmetrical
  • If NO ❌ → Not symmetrical

🧠 Fun Activity

  • Draw a line in the middle of a picture.
  • Color both sides the same.
  • Check if your picture is symmetrical!
