Seven.
A heptagon is a figure with 7 sides. Also, if by corner you mean edges, we can find that. There's the edges of the heptagonal base. So there's 7. Then we have the edges of where the lateral faces meet each other. There's another 7. You have 14 edges in a heptagonal pyramid. If, in fact, you meant "corners", then we add in the vertex (or apex) of the pyramid. Then you will have 15 "corners".
A nonagon based pyramid. An octagon based dipyramid. An octagonal base with a double-apex "pyramid". A heptagonal base with a triple-apex "pyramid". A heptagonal pyramid with a double-apex "pyramid" on the other side. A pentagonal prism. There are many more.
One possibility is a heptagonal pyramid - with a heptagon as a base and seven triangular faces meeting at the apex.
A triangular-based pyramid has six edges: three in the base triangle and three from there to the apex.
The base of a square pyramid is a square and its edges are parallel. The sides are not parallel since they intersect at the apex.
A pyramid is a generic term used to describe a polyhedron with a polygonal base and a number of triangles rising from that base to meet at an apex. A pyramid whose base is a polygon with n-sides (or vertices) has n+1 faces, n+1 vertices and 2n edges, where n ≥ 3. So a pyramid with a heptagonal base will have 8 vertices!
eight * * * * * A triangular pyramid has six edges: three edges that form the triangular base and then three more edges going up from each vertex of the base to the apex (peak) of the pyramid.
A square-based pyramid - line the ones in Egypt - has four edges on its base and four vertical edges rising from the base to the apex - so it has 8 edges.
no, it has 8 : the four sides of the base and the four edges from the apex to the base.
Yes! Four at the base, and four edges reaching to the point, or apex.
A square pyramid has 5 * * * * * The above answer has nothing to do with the question. A triangular pyramid has 6 edges. Three edges form the triangular base. Another 3 edges rise from the three vertices of the triangular base to the apex of the pyramid. 3 + 3 = 6. OK?
A triangular-based pyramid has six edges: three in the base triangle and three from there to the apex.
