HEIGHT OF A PRISM OR CYLINDER: The length of the shortest line segment from a base of a prism or cylinder to the plane containing the opposite base. The height is perpendicular to the bases.

Catalan: Altura d’un prisma o cilindre Spanish: Altura d’un prisma o cilindre

 

HEIGHT OF A PYRAMID OR CONE: The length of the shortest line segment from the apex of a pyramid or cone to the plane containing the base. The height is perpendicular to the base.

Catalan: Altura de la piràmide o con Spanish: Altura de una pirámide o cono

 

 

 

 

ICOSAHEDRON: A polyhedron with 20 faces. An icosahedron with equilateral triangle faces is one of the five regular polyhedrons. Catalan: Icosàedre Spanish: Icosaedro

 

IMPERIAL: Traditional system of measurement used in Great Britain and its colonies.

Catalan: Imperial Spanish: Imperial

 

 

 

 

PINT: Imperial unit of volume or capacity used to measure liquid or dry goods. In liquid measurements, containing 4 gills.

Catalan: Pinta Spanish: Pinta

 

PRISM: A polyhedron with two parallel and congruent polygonal regions for bases and lateral faces formed by all the line segments with endpoints on corresponding edges of the bases. The lateral faces are all parallelograms. Lateral faces intersect at lateral edges. In a right prism, the lateral faces are rectangular.

Catalan: Prisma Spanish: Prisma

 

PYRAMID: A polyhedron made up of any polygonal region for a base, a vertex (apex) not in the plane of the base, and all of the line segments with one endpoint at the apex and the other on an edge of the base. All faces except perhaps the base are triangular. Catalan: Piràmide Spanish: Pirámide

 

 

 

 

VERTEX: The point at which the rays of an angle, the sides of a polygon, or the edges of a polyhedron meet. Plural is vertexes or vertices.

Catalan: Vèrtex Spanish: Vértice

 

VOLUME: The amount of space occupied by a 3-dimensional figure. Same as capacity.

Catalan: Volum Spanish: Volumen
