| A | B |
|---|
| Polyhedron | Solid bounded by polygons |
| How is a Polyhedron regular? | If all faces are congruent regular polygons (cube is a regular polyhedron) |
| Cross Section | Shape you see when a solid is sliced into 2 parts |
| Net | A plane figure that can be folded to create a solid |
| Eulers Number | Relationship between faces, vertices, and edges in a polyhedron |
| Prism | Polyhedron with 2 congruent faces, called bases, that lie in parallel planes |
| Lateral Faces | Parallelograms formed by connecting the corresponding vertices of the bases |
| Right Prism | Lateral edges are perpendicular to the bases |
| Surface Area | In a polyhedron, the sum of the areas of its faces |
| Cylinder | A solid with congruent circular bases that lie in parallel planes |
| Lateral Area | Sum of area of the lateral faces |
| Lateral Area of a Cylinder | Area of curved surface |
| Pyramid | Polyhedron whose base is a polygon and lateral faces are triangles with a common vertex |
| Cone | Circular base |
| Right cone | height meets base at its center |
| Volume | The number of cubic units the interior of a solid contains |
