Platonic Solids Glossary
Solid: Solid A body is one of the four aggregation states of matter , characterized in that resists changes in shape and volume.
Platonic: Plato The word refers to something on the Greek philosopher Plato (427-347 BC). Plato in Greek and is the root Πλάτων πλατος (plates = broad, flat) found in words such as plate and silver.
Platonic Solid: The Platonic solids, also known as Platonic bodies , cosmic bodies, Pythagorean solids or polyhedra Plato are characterized as geometric polyhedra convex whose faces are equal regular polygons and whose vertices are attached to the same number of faces.
Polyhedron: A polyhedron is a solid flat surfaces (the word comes from Greek, poly meaning "many" and "edro means" face "). Each flat face (just "face") is a polygon. So to be a polyhedron need not have any curved surface .
Convex : The convexity of a curve or area is the area that resembles the exterior of a circle or a spherical surface.
convex polyhedron: A polyhedron convex is one in which the segment joining any two points is contained in the polyhedron.
Polygon : plane geometric figure bounded by a closed traverse is not cut herself.
Regular Polygon: Polygon in which all sides are of equal length and all angles are confined in a circle.
Convex: Describes surface has its central part with respect to the observer outstanding .
Tetrahedron: A tetrahedron is a polyhedron with four faces. With this number of heads is bound to be a convex polyhedron, and triangular faces, three of them were found at each vertex.
hexahedron: A hexahedron is a polyhedron with six faces. With this number of heads is bound to be a convex polyhedron, and their faces are to be five-sided polygons or less.
Octahedron: An octahedron is a polyhedron with eight faces. With this number of faces can be a convex polyhedron or a concave polyhedron. Their faces are to be seven-sided polygons or less.
Dodecahedron: A dodecahedron is a twelve-sided polyhedron, convex or concave. Their faces are to be polygon of eleven sides or less.
Icosahedron: An icosahedron is a twenty-sided polyhedron, convex or concave. Their faces are to be nineteen-sided polygons or less.
Prisma: A prism is a polyhedron composed of two equal and parallel faces called bases, and lateral faces are parallelograms.
Parallelogram: A parallelogram is a special type of quadrilateral (polygon has four sides) whose sides are parallel in pairs.
Angle: The plane formed by two or lines that intersect. Is the form or content between two visual to two stars. The angular distance is measured in degrees, minutes and seconds of arc. A circumference measures 360 º. One degree equals 60 '(minutes) and 1' is equal to 60 "(seconds).
Arista: Arista (Latin: groin) is on the line segment geometry where two planes intersect. By extension also known by this name to the common segment with two neighboring faces of a polyhedron, and form to get in touch.
Octahedron: An octahedron is a polyhedron with eight faces. With this number of faces can be a convex polyhedron or a concave polyhedron. Their faces are to be seven-sided polygons or less.
Dodecahedron: A dodecahedron is a twelve-sided polyhedron, convex or concave. Their faces are to be polygon of eleven sides or less.
