2D Shapes
2D shapes are flat shapes. They have length and width but no thickness. Each shape has a different number of sides and angles.
Your goals
- ✓You can learn about flat shapes and their properties.
- ✓You can use polygon, vertex correctly.
- ✓You can count sides and vertices, then check side lengths and angles.
Words to know
- polygon:
- A closed 2D shape made only from straight sides.
- vertex:
- A corner where two sides meet.
Examples
- 1Triangle: 3 sides. Square: 4 equal sides. Pentagon: 5 sides.
- 2Rectangle: 4 sides (2 pairs of equal sides). Hexagon: 6 sides.
Check these
- • Do not name a shape only from how it is turned.
- • Keep every number, symbol, label, and unit in its correct place.
- • Show enough working to check how you reached your answer.
Helpful habits
- • Read the whole question before choosing what to do.
- • Show one clear step at a time and check each step.
- • If you are stuck, draw a model, try smaller numbers, or revisit the example.
Now try your own
Create your own 2d shapes example, solve it, and explain how you checked it.
