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.
Best Answer: With a triangular base and triangular sides there will be: - 4 faces (including base), - 6 edges (meeting of any two faces) - 4 vertices's ( corner points) Edit; the above more correctly applies to a polygon. As you specified a prism which requires a pair of parallel faces the answer would change.
