Exploring Shapes and Space

Geometry is about shapes, their sizes, and how they fit together. You'll work with triangles, rectangles, circles, and more.

Measuring Perimeter

The perimeter is the distance around a shape. Add up all the sides!

Finding Area

Area is the space inside a shape.

• Rectangle: \( \text{Area} = \text{length} \times \text{width} \)
• Triangle: \( \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} \)
• Circle: \( \text{Area} = \pi r^2 \)

Why Geometry Matters

Geometry is used in art, sports fields, architecture, and even video game design.
