Shapes (Grade 5)
More polygons + 3D shapes (faces, edges, vertices).
🎯 What you'll learn
- ✓Name regular polygons up to 10 sides
- ✓Count faces / edges / vertices
2
Cube
6 faces · 12 edges · 8 vertices.
🎲
3
Square pyramid
5 faces · 8 edges · 5 vertices.
🔺 base = square
4
3D shape nets
If you 'unfold' a 3D shape onto paper, you get its net.
🎲 → ⛶ flat
5
Surface area
Add up the area of every face of a 3D shape.
Σ face areas
6
Symmetry
A shape has line symmetry if you can fold it so the halves match.
