Study Notes
Geometry Basics
- Geometry is the branch of mathematics that studies the sizes, shapes, positions, angles, and dimensions of things.
Dimensions of Shapes
- 2D shapes in geometry are flat and have two dimensions, such as length and width.
- Not all shapes are 2D; for example, a sphere is not a 2D shape.
Open and Closed Shapes
- Open shapes in geometry are those that do not form a complete circuit or do not have a boundary.
- Closed shapes in geometry are those that form a complete circuit or have a boundary, such as a circle or a triangle.
Three-Dimensional Shapes
- Three-dimensional shapes in geometry are those that have three dimensions, such as length, width, and height.
- Examples of three-dimensional shapes include cubes, spheres, and pyramids.
