Do pyramids have perpendicular faces ?
no , pyramids need not have only squares as their base. the base of a pyramid can be any polygon.
It does: on its base.
no, the three sides converge at the top. and the bottom does not have an opposite side. Pyramids can be constructed on a square/rectangle base or a triangle base. Faces are parallel or otherwise accordingly
Vertices in a PyramidA tetrahedron is the simplest pyramid. It has four vertices and four faces.A pyramid, the same general shape as monumental structures in Egypt, with a square base and four triangular faces meeting at an apex has 5 vertices.However, a pyramid can have any polygon as its base. A pyramid with an n-sided polygon as base would have n+1 vertices.So a twelve sided pyramid would have 13 vertices I think there are 4......* * * * *One more than the number of vertices (corners) on the base. A triangular pyramid has 3+1 = 4 vertices, a rectangular pyramid has 4+1 = 5 and so on.It depends. There are different kinds of pyramids, with different amounts of vertices (the plural for vertex). There are square pyramids, with square bases, triangle pyramids, with triangular bases, hexagon pyramids, octagon pyramids, pentagon pyramids... here are a few answers, though: Square pyramids have five vertices. Triangle pyramids have four. Hexagon pyramids have seven, octagon pyramids have nine, pentagon pyramids have six.6

A square pyramid is a pyramid with a square base. It has 4 outer faces, all of which are triangles, that meet at the same point perpendicular to the centre of the base. All pyramids have at least 4 faces (including the base), where the outer faces are all triangular while the base can be trilateral, quadrilateral, or any other polygon. The quadrilateral form (the square pyramid) is the most common form of pyramid, and is the form associated with the Egyptian pyramids.
It means that it has a rectangular base rather than a square 1 :)
a square
Correct
It does: on its base.
The shape of its base. So you can get triangular pyramids, square pyramids and so on.
A pyramid is not a square, but it has a square base formed by four triangular sides. Pyramids like the ones at Giza in Egypt are five-sided geometric shapes (pentahedrons).
There are various types of pyramids, including regular pyramids (with a regular polygon as the base and congruent isosceles triangles as the faces), right pyramids (with the apex directly above the center of the base), and oblique pyramids (where the apex is not directly above the center of the base). Pyramids can also be classified based on the shape of their base, such as square pyramids, triangular pyramids, pentagonal pyramids, etc.
No.
