Shapes, Space, and Measurement

Geometry helps you understand the world around you, from the playground to your bedroom. It’s all about shapes, sizes, and how things fit together.

Important Concepts

• Points, Lines, and Angles: The basics of all shapes.
• Polygons: Shapes with straight sides, like triangles, rectangles, and pentagons.
• Area and Perimeter: Area is the space inside a shape. Perimeter is the distance around it.

Real-World Applications

• Designing a garden (measuring area)
• Building a picture frame (calculating perimeter)
• Navigating a map or drawing

Measuring Tricks

Remember: \( \text{Perimeter of rectangle} = 2(l + w) \) and \( \text{Area} = l \times w \)!
