no... they do not have right angles connected to the sides

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
