Shapes and Spaces

Geometry is all about shapes, sizes, and spaces. Measurement tells us how big or small things are.

Basic Shapes

• 2D Shapes: Triangles, squares, rectangles, circles.
• 3D Shapes: Cubes, spheres, cylinders, pyramids.

Perimeter, Area, and Volume

• Perimeter: The distance around a shape.
• Area: The amount of space inside a 2D shape.
• Volume: The space a 3D object occupies.

Useful Formulas

• Area of a rectangle: \( A = l \times w \)
• Area of a triangle: \( A = \frac{1}{2} b h \)
• Volume of a box: \( V = l \times w \times h \)

Measurement Tools

Use rulers, measuring tapes, and protractors to measure objects and angles in real life.

Real-Life Applications

Geometry and measurement help with tasks like building, decorating, and gardening.
