Most of the pyramids were mad at different moments
no not all pyramids are polyhedron because each pyramid has a different shape. so no each pyramid is not a polyhedron * * * * * Yes they are.
yes! there are secret passage ways all over!
Both cones and pyramids have one base and they all have a vertex, or they all come to a point. That is what makes them alike. What make them different is that a cone has one curved edge at its base, and a pyramid has 6 to 8 edges which is not curved

The pyramids in Egypt were all built the same way. They were square based and in porportion to the golden ratio. Although pyramids in the middle east and Persia, mor commonly known as ziggurats, were round and tiered. This is because they were built by a different civilization and in a different time pyramid. And also, the South Americans buit square based tiered pyramids, because they too had different architecture methods and lived in a different time period.
all the bases of a pyramids are polygon
The base is different. A rect. pyramid has a rectangle as a base. Because the sides are different length for a rectangle, the triangles will not all be congruent (equal). A square pyramid has a square as the base. All sides of the square are the same length, so all the triangular sides of the pyramid will be congruent.
If they were not different they would all be called the same thing!If they were not different they would all be called the same thing!If they were not different they would all be called the same thing!If they were not different they would all be called the same thing!
