solid Geometry Glossary
- Area cross-section - A two-dimension plane slice of a three-dimension plane.
- Volume - The space occupied by a mass.
solid Geometry Types
- Polyhedron - Is a solid with no curved edges or sides.
- Prism Solids - Prisms are solids with two congruent parallel polygon ends that are exactly the same.
- Oblique prism - Has with both bases not alligned above each other and the center not at 90° to the other base center.
- Right prism - Has both bases directly above each other and having the centers at 90° to each others base.
- Cube - Is a regular polyhedron with square faces.
- Right Hexagonal Prism - Has hexagonal bases and each face is a regular polygon with equal sides and equal angles.
- Right Octagonal prism -
- Right Pentagonal Prism - Has pentagonal bases and each face is a regular polygon with equal sides and qual angles.
- Right Rectangular Prism - Has six faces that are rectangles with equal sides and equal angles.
- Right Square Prism - Has square bases, four faces that are rectangles with equal sides and equal angles.
- Right Triangular prism -
- Pyramid Solids - Pyramids are solids with one polygon base and lateral faces that taper to an apex.
- Oblique Pyramid - The apex is not alligned above the center at 90° to the base.
- Right Pyramid - The apex is directly above the center at 90° to the base.
- Right Pentagonal Pyramid - Has a pentagon base and the apex alligned above the center of the base.
- Right Square Pyramid - Has a square base and the apex alligned above the center of the base.
