Regular Polyhedron: A polyhedron made up of congruent regular polygons
Types of Polyhedrons
Prism: A polyhedron with two congruent parallel polygon bases connected by quadrilateral faces.
Base: two parallel faces in a prism
Lateral faces: Faces that are not bases
Lateral edges: where the lateral faces meet

Ways to classify prisms:Edges in an oblique prism are not perpendicular to the base
Altitude of a prism: the perpendicular segment from one base to the plane containing the other base. The length of the altitude is called the height of the prism.

Pyramid: a polyhedron with one polygon base and triangular lateral faces that meet at a point
The altitude of a pyramid is IN the pyramid. Slant height is the
altitude of the triangles ON THE SIDE of the pyramid.
Altitude of a pyramid: the perpendicular segment from the vertex to the base
Slant height of a pyramid: the length of each triangular face

11.2 NotesSphere: the set of all points in a space at a given distance from a given point
center
radius
Hemisphere: half of a sphere
The Great Circle: the face of a hemisphere
Cylinder
Axis: the segment connecting the centers of the circles.
Altitude: A perpendicular segment from one base to the plane containing the other.

Right cylinder: when the Oblique cylinder: when axis is perpendicular to the axis is notthe bases. perpendicular to the
bases.
Cone
Right cone- when a there is a perpendicular line from the vertex to the center of the base.
Oblique cone- Cones that are not right.
