How many lateral faces do pyramids have? Three or more, as many as the number of sides of the base. Pyramids can have base that are triangles, squares rectangles, or any planar polygon.
Each base edge and apex form a triangle, called a lateral face. It is a conic solid with polygonal base. A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2 n edges. All pyramids are self-dual. A right pyramid has its apex directly above the centroid of its base. Nonright pyramids are called oblique pyramids.
