How many corners does the heptagonal pyramid have?

Answer 1

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".
