It is a Pentahedron.
It can be any type of pyramid.
A square one
It depends on what type of pyramid, if it is a triangular based pyramid then 6 but it all relies on the base realy
TriangleTrapezoidTrapeziumTridecagon or triskaidecagon (13 sided polygon)Tetradecagon or tetrakaidecagon (14 sided polygon)Triangular prismTriangular pyramid or triangular-based PyramidTridecagonal pyramid or tridecagon-based pyramidTetrahedronTorus... and a whole host of polyhedrons of weird shapes or many sides such asTetradecahedron (14 faced polyhedron) Triacontahedron (30 faced polyhedron)Triangular Orthobicupola (consisting of eight equilateral triangles and six squares) Triaugmented Triangular Prism (composed of 14 equilateral triangles)... any truncated polyhedron - one where you truncate the vertices of a polyhedron to form new face, for example:Truncated tetrahedronTruncated cube (which also happens to be a type of Tetradecahedron - another geometric shape staring with a "t"Truncated octahedron
It's has all acute angles
Yes and a triangular based pyramid is a tetrahedron
It is a square based pyramid.
It is a square based pyramid which also has 8 edges
It can be any type of pyramid.
The pyramid is SQUARE BASED and the sides are triangles. Unless you're getting technical, and you're counting a square as a 'special type of rectangle', then the answer is one.
an elongated square pyramid- here is a website with pictures(http://en.wikipedia.org/wiki/Elongated_square_pyramid )
A square based pyramid has 5 faces, 8 edges and 5 vertices
Pyramids are a type of polyhedron that has a polygonal base with triangles extending from it to form an apex. The pyramids of Egypt would be examples of square pyramids because the bottom of them are squares. Likewise, you could have a pentagonal pyramid, hexagonal pyramid, pentagrammic pyramid etc.
No- A square is a plane figure- it is a type of polygon not a polyhedron.
A pyramid can have 4 or more faces. A pyramid, with a n-sided polygon as base will have n+1 faces. The polygon with the least number of sides is a triangle and a triangular pyramid (tetrahedron) has 4 faces. A square based pyramid has 5 faces, and so on.
A square one
It depends on what type of pyramid. Their is an square pyramid, a rectangular pyramid, a pentagonal pyramid, etc.
