Solid geometry is a three-dimensional figure with connecting edges on multiple planes.  The surface of each two-dimensional plane is called a face.

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.
    • Right Triangular Pyramid  -  Has a triangle base and the apex alligned above the center of the base.
  • Wedge Solids  -  Wedges have two triangle ends and three polygon sides.
    
    • Isosceles Triangle Wedge  -  Has three rectangle sides and two isoscelees triangle sides.
    • Right Triangle Wedge  -  Has two right triangle ends and three rectangle sides.

• Non-polyhedron  -  Is a solid with curved edges or sides.
  
  • Cone  -  Cones have one circular base tapering to an apex.
    • Oblique Cone  -  The apex is not alligned above the center at 90° to the base.
    • Right Cone  -  Has a circle base with the apex alligned at 90° above the center of the base.
  • Cylinder  -  Cylinders have two circular parallel congruent bases.
    
    • Oblique Cylinder  -  Both bases not alligned above each other and the center not at 90° to the other base center.
    • Right Cylinder  -  Both bases direictly above each other and having the centers at 90° to each others base.
    • Right Elliptic Cylinder  -  No parallel lines and both bases are ellipses.
    • Right Hollow Cylinder  -  A hollow core with both bases direictly above each other and having the center at 90° to each others base.
  • Ellipsoid  -  Ellipsoids have a spherical like shape with an ellipse cross section.
    
  • Paraboloid  -
    
    • Elliptic Paraboloid  -  Has a u-shaped curve with an elliptical base.
  • Sphere  -  All points equally spaces from a given point of a three dimensional solid.
  • Torus  -  Is shaped like a donut.
