Moons of Mars. The two moons of Mars are Phobos and Deimos. Both moons were discovered in 1877 by Asaph Hall and are named after the characters Phobos (panic/fear) and Deimos (terror/dread) who, in Greek mythology, accompanied their father Ares, god of war, into battle. Ares was known as Mars to the Romans.
A triangular prism is a prism composed of two triangular bases and three rectangular sides. It is a pentahedron. It is implemented in the Wolfram Language as PolyhedronData[TriangularPrism]. The triangular prism has nine distinct nets, as illustrated above.
A prism is a polyhedron that has two congruent parallel polygons as its bases. The other faces of a prism are parallelograms, most often rectangles. A prism is named for the shape of its base. For instance, this prism is called a hexagonal prism, because its two bases are hexagons.Visualizing three-dimensional figures is an important part of geometry, and it helps to build mental math muscle. prism is named for the shape of its base.
