Across
- 3. a solid figure that has one special face called the base. All of the other faces are triangles that meet at a single vertex called the apex.
- 4. The figure formed by intersecting a solid with a plane.
- 6. a three-dimensional figure with a circular base and a point not in the plane of the base called the apex. Each point on the base is connected to the apex by a line segment.
- 8. a three-dimensional figure in which all cross-sections in every direction are circles.
- 9. the ratio (quotient) of the length of the opposite leg to the length of the adjacent leg.
Down
- 1. a solid figure composed of two parallel, congruent faces (called bases) connected by parallelograms.
- 2. a three-dimensional figure with two parallel, congruent, circular bases, formed by translating one base to the other. Each pair of corresponding points on the bases is connected by a line segment.
- 5. the ratio (quotient) of the length of the opposite leg to the length of the hypotenuse.
- 6. the ratio (quotient) of the length of the adjacent leg to the length of the hypotenuse.
- 7. The mass of a substance per unit volume.
