Across
- 1. A 3-D figure that has one circular base. The points on this circle are joined to one point outside the base.
- 5. three-dimensional figure made of flat polygon-shaped surfaces
- 6. A plane figure pattern which, when folded, makes a solid.
- 7. A designated side of a polygon to which the height is drawn perpendicular; one of the two parallel and congruent faces on a prism.
- 10. The number of cubic units needed to a fill a solid figure.
- 11. The segment from a vertex perpendicular to the line containing the opposite side, perpendicular distance between the bases o a solid.
- 13. A flat surface of a polyhedron.
- 14. The point of intersection of the edges of a polyhedron.
Down
- 1. 3-D figure that has two circular bases which are parallel and congruent.
- 2. The sum of the areas of each face of a polyhedron.
- 3. A 3-D figure such that every point is the same distance from center.
- 4. A polyhedron whose base can be any polygon and whose faces area triangles.
- 8. The line segment where two faces of a polyhedron meet.
- 9. A unit measuring volume, consisting of a cube with edges one unit long.
- 12. A polyhedron with two congruent and parallel polygon-shaped faces.
