| A polyhedron with two congruent parallel faces. | prism |
| A drawing that shows the top view, the front view, and the right-side view of a three-dimensional figure. | orthographic |
| A perpendicular segment of a prism that joins the planes of the bases. | altitude |
| The segment that is the intersection of two faces of a polyhedron. | edge |
| A drawing of a three-dimensional object that shows a right-front corner view of the figure. | isometric |
| A three-dimensional figure that has a circular base, a vertex not in the plane of the base, and a curved lateral surface. | cone |
| The two congruent parallel faces of a prism. | bases |
| The faces of a prism that might not be parallel but are always parallelograms. | lateral |
| A three-dimensional figure with two congruent circular bases tha lie in parallel lines. | cylinder |
| A polyhedron in which one face is a polygon and the other faces are triangles with a common vertex. | pyramid |
| A drawing that shows the base of a structure and the height of each part. | foundation |
| The polygons that make up the sides of a polyhedron. | faces |
| The length of the altitude of a prism. | height |
| A three-dimensional figure whose surfaces are polygons. | polyhedron |
