Prisms and Pyramids: Polyhedral shapes like cuboids, cubics, and pyramids are common in 3D geometry. These shapes have flat faces and straight edges.
- Spheres: A sphere is a round object with all points on the surface equidistant from the center.
- Cylinders and Cones: These are shapes with a circular base that extends vertically. A cylinder has a uniform radius, while a cone tapers to a point.
- Tetrahedrons, Octahedrons, Dodecahedrons: These are polyhedra with various types of faces (triangular, pentagonal, etc.), and their properties are important in various scientific and engineering fields.
- Coordinate Systems:
- Cartesian Coordinates: The most common coordinate system in 3D geometry, where every point is represented by an ordered triplet (x, y, z).
- Polar Coordinates: These are used for circular or spherical objects and work by describing points in terms of distance and angle from a central reference point.
- Spherical Coordinates: A more advanced system used in 3D space where points are described by their radial distance and angular coordinates (theta and phi).
