📚 What are Flat Shapes?
Flat shapes, also called 2D shapes, are shapes that you can draw on a piece of paper. They only have two dimensions: length and width. Think of them as outlines or shadows.
- 📐 Examples: Circles, squares, triangles, and rectangles.
- ✏️ How to identify: You can trace them easily on paper.
- 🖼️ Real-world example: A drawing of a pizza.
📦 What are the Faces of Solid Objects?
Solid objects, also called 3D shapes, are shapes that take up space. They have three dimensions: length, width, and height. The faces of solid objects are the flat shapes that make up their surface.
- 🧱 Examples: Cubes, spheres, pyramids, and cylinders.
- 🖐️ How to identify: You can hold them in your hand.
- 🎁 Real-world example: A gift box (the sides are the faces).
