Question | Answer |
---|---|

Apex | In a pyramid or cone, the vertex opposite the base. |

Base of a Parallelogra | The side of a parallelogram to which an altitude is drawn. |

Base of a Prism or Cylinder | Either of the two parallel and congruent faces that define the shape of a prism or cylinder. |

Base of a Pyramid or a Cone | The face of a pyramid or cone that is opposite its apex. |

Calibrate | To divide or mark a measuring tool with gradations, such as the degree marks on a thermometer. |

Cone | A 3-dimensional shape that has a circular base, a curved surface, and one vertex, which is called the apex. |

Cube | A polyhedron with 6 square faces. A cube has 8 vertices and 12 edges. |

Cylinder | A 3-dimensional shape that has two circular or elliptical bases that are parallel and congruent and are connected by a curved surface. A can is a cylinder shape. |

Cylinder | A 3-dimensional shape that has two circular or elliptical bases that are parallel and congruent and are connected by a curved surface. A can is a cylinder shape. |

Edge | A line segment where two faces of a polyhedron meet. |

Face | A flat surface on a polyhedron. |

Face | A flat surface on a polyhedron. |

Geometric Solid | A 3 dimensional shape, such as a prism, pyramid, cylinder, cone, or sphere. Despite its name, a geometric solid is hollow; it does not contain the points in its interior. |

Polyhedron | A geometric solid whose surfaces (faces) are all flat and formed by polygons. Each face consists of a polygon and the interior of the polygon. A polyhedron does not have any curved surface. |

Polyhedron | A geometric solid whose surfaces (faces) are all flat and formed by polygons. Each face consists of a polygon and the interior of the polygon. A polyhedron does not have any curved surface. |

Prism | A solid with two parallel faces, called bases, which are congruent polygons, and other faces that are all parallelograms. Prisms are named for the shape of their base. |

Pyramid | A solid in which one face, the base is any polygon and all the other faces are triangles that come together at a point called the vertex or apex. Pyramids are named for the shape of their base. |

Pyramid | A solid in which one face, the base is any polygon and all the other faces are triangles that come together at a point called the vertex or apex. Pyramids are named for the shape of their base. |

Sphere | The set of all points in space that are a given distance from a given point. The given point is the center of the sphere and the given distance is the radius. |

Sphere | The set of all points in space that are a given distance from a given point. The given point is the center of the sphere and the given distance is the radius. |

Surface Area | The measure of the surface of a 3-dimensional figure. |

Vertex (vertices or vertexes) | The point where the rays of an angle, the sides of a polygon, or the edges of a polyhedron meet. |
