Given the question: Information: - Geometry (from the ; "geo-" "earth", "-metron" "measurement") is a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space. A mathematician who works in the field of geometry is called a geometer. - In geometry, a tetrahedron (plural: tetrahedra or tetrahedrons) is a polyhedron composed of four triangular faces, six straight edges, and four vertex corners. The tetrahedron is the simplest of all the ordinary convex polyhedra and the only one that has fewer than 5 faces. - A Heronian tetrahedron or perfect tetrahedron is a tetrahedron whose edge lengths , face areas and volume are all rational numbers . The faces must therefore all be Heronian triangles . A regular tetrahedron ( one with all faces being equilateral ) with all sides rational is not a Heronian tetrahedron because its face areas and volume are not rational numbers . 117 is the smallest possible length of the longest edge of a perfect tetrahedron with integral edge lengths . Its other edge lengths are 51 , 52 , 53 , 80 and 84 . - In geometry, a Heronian triangle is a triangle that has side lengths and area that are all integers. Heronian triangles are named after Hero of Alexandria. The term is sometimes applied more widely to triangles whose sides and area are all rational numbers. - In elementary geometry, a polyhedron (plural polyhedra or polyhedrons) is a solid in three dimensions with flat polygonal faces, straight edges and sharp corners or vertices. The word polyhedron comes from the Classical Greek , as "poly-" (stem of , "many") + "-hedron" (form of , "base" or "seat"). What is the relationship between 'heronian tetrahedron' and 'hero of alexandria'?
The answer is:
named after
