The short answer is no. Strictly speaking, a pyramid is the generic term. A pyramid has a base formed from a polygon connected to a point called the apex. A tetrahedron is a pyramid with the base of a triangle. Thus a tetrahedron is a specific example of a pyramid.
The most simple pyramid is a tetrahedron. This pyramid has four faces, all triangles. If the pyramid was a cone then it could have two faces.
This 3D shape could be a square based pyramid.
It could be a triangular based pyramid whose technical name is a tetrahedron.
triangular pyramid. how do you not know. >:/ * * * * * Very amusing but, if the person who wrote the first answer was less bent on being sarcastic, s/he could have given the proper answer: it is called a tetrahedron.
The only thing I can come up with would be a tetrahedron. You could make a pyramid with a square (open) base, I guess.
A tetrahedron.
There are quite a few ways you could find the height of a square pyramid. You could measure the sides for example.
No. A cone could be considered the limiting case of a pyramid, but a hemisphere is not, because the lines joining the base to the apex are not straight.
No. Erm...kind of. One example could be a triangular prism
Polygons aren't normally described as having faces Polyhedrons are normally described as having faces So it could be a tetrahedron which is a triangular based pyramid
Yes, the Great Pyramid of Giza is a square pyramid. From a birds eye view, you could see that the bottom is in the shape of a square. See: http://www.mathsisfun.com/geometry/pyramids.html
