In trigonometry,
we call it a rectangular pyramid.
A rectangular based pyramid
A rectangular pyramid.
octagonal pyramid :)
A pyramid
Tetrahedron has three sides and a base all triangular.
It depends on what type of shape you are trying to find the area. If it is a rectangle, you do base times height. For triangles, you do base times height divided by two. For a circle, it is Pi*R^2.
a square pyramid (i found it in my sons math book !)
There is a contradiction in your question. If the base has four equal sides then is it a square so not all the faces are Triangles. However if the base is a square and the rest of the faces are triangles then your object is a "Square-based Pyramid"
