2D shapes like triangles, squares, rectangles, and circles have different numbers of sides and corners, defining their properties.
Quick revision
Remember these!
- Lines: straight or curved.
- They can be horizontal, vertical, slanting.
- 2D shapes: triangles, squares, rectangles, circles.
- They have specific sides and corners.
- 3D shapes: cubes, spheres, cylinders.
- They have length, width, height.
- This differs from flat 2D shapes.
- Understanding shapes helps recognise patterns.
