Everyday examples of shapes made from smaller shapes

📚 Quick Study Guide

• 📐 Basic Shapes: Remember the core shapes: squares, triangles, circles, rectangles.
• 🧩 Tessellations: Patterns formed by repeating shapes that fit together without gaps or overlaps.
• 🧱 Complex Shapes: Many objects are constructed by combining basic shapes.
• ➕ Addition of Areas: The area of a complex shape is the sum of the areas of its component shapes. $Area_{total} = Area_1 + Area_2 + ... + Area_n$
• ➗ Decomposition: Breaking down a complex shape into simpler ones to calculate properties such as area or perimeter.
