Explore shapes, areas, and spatial relationships
Geometry is the study of shapes, sizes, angles, and positions. It's all around us - from the rectangle of your screen to the circle of a wheel!
Key Concepts:
🏠 Architecture: Houses use rectangles, triangles for roofs, and circles for windows
🎨 Art: Artists use geometric shapes to create patterns and designs
🏈 Sports: Soccer balls use pentagons and hexagons, basketball courts are rectangles
🌍 Nature: Honeycomb hexagons, flower petals in circles, snowflake symmetry

Let's explore the fundamental shapes that form the building blocks of geometry!
4 equal sides, 4 right angles
4 sides, opposite sides equal
3 sides, 3 angles
Perfect round shape
How many sides does a triangle have?
Perimeter: The distance around the outside of a shape
Area: The space inside a shape
Rectangle: length = 6, width = 4
Perimeter = 2 × (6 + 4) = 2 × 10 = 20
Area = 6 × 4 = 24
Rectangle with length = 8 and width = 5
What is the area?
An angle is formed when two lines meet. We measure angles in degrees (°).
What type of angle is shown above?
3D shapes have length, width, and height. They take up space and have volume.
6 square faces, all equal
2 circular bases, curved side
Square base, triangular faces
Perfectly round, like a ball
A cube has sides of length 4 units.
What is the volume?
