15 Cards in this Set

  • Front
  • Back
Cube
A regular polyhedron with six faces, all of which are congruent squares.
Cone
A surface that includes a simple closed curve and the segments that join all the points on that curve with a single fixed point not in the plane of the curve.
Cylinder
A geometric surface composed of two congruent simple closed curves lying in parallel planes and segments of parallel lines joining the curves.
Face
A polygon in a polyhedron.
Edge
The intersection of two polygons in a polyhedron.
Polyhedron
A simple closed surface composed of regions of intersecting planes--these regions are polygons.
Radius of a Sphere
A segment with one endpoint at the center of a sphere and the other endpoint on the sphere.
Prism
A polyhedron composed of two congruent polygons that lie in parallel planes and the segments that are part of parallel lines that join the congruent polygons.
Pyramid
A polyhedron composed of a polygon and the segments that join that polygon with a fixed point not in the plane of the polygon.
Radius of a Sphere
A segment with one endpoint at the center of a sphere and the other endpoint on the sphere.
Regular Polyhedron
A polyhedron whose faces are congruent regular polygons
Regular Pyramid
A pyramid whose base is a regular polygon and whose altitude intersects the plane of its base at the center of the base.
Right Circular Cone
A circular cone whose altitude intersects with the plane of the base at the center of the base.
Right Circular Cylinder
A circular cylinder whose lateral edges are perpendicular to the planes that contain the bases.
Sphere
A surface whose points all lie an equal distance from a fixed point in space.
