Symmetrical Shapes!

Mirror Magic

Grade 5 Ontario Math πŸ“š β€’ Geometry & Spatial Sense

Hello my wonderful Grade 5 superstar! πŸ‘‹

I'm Kashef and today we're exploring Symmetrical Shapes! Symmetry is when one half of a shape looks exactly like the other half β€” like a mirror! Many beautiful things in nature and art are symmetrical. Ready to find the mirror line? Let’s go! πŸš€

πŸͺž What is Symmetry?

A shape is symmetrical if you can fold it so both halves match perfectly.

This fold line is called the Line of Symmetry.

This heart has 1 line of symmetry.

🌟 Types of Symmetry

1. Line Symmetry (Reflection)
One half is a mirror image of the other.

2. Rotational Symmetry
You can rotate the shape and it still looks the same.

Examples:

  • Square β†’ 4 lines of symmetry + rotational
  • Rectangle β†’ 2 lines of symmetry
  • Circle β†’ infinite lines of symmetry

🎯 Let’s Find Symmetry!

1. How many lines of symmetry does a square have?

4 lines

2. Does the letter "A" have symmetry?

Yes β€” 1 vertical line of symmetry

3. Which letter has rotational symmetry? (H, O, or S)

O (and H)
