## Solid Geometry

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 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 equal 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.
