The only one i can think of is the square - based pyramid, with 4 triangular faces and 1 square
They can be any shape ! We have square and rectangular ones in my town (and there's at least a couple of triangular ones too !)
A pyramid is not a square, but it has a square base formed by four triangular sides. Pyramids like the ones at Giza in Egypt are five-sided geometric shapes (pentahedrons).
A triangular prism has two triangular faces and three rectangular ones.
Juan Ponce de Leon's famous expedition to Florida included three ships.Two were caravels; the Santiago, which was the flagship, and the Santa Maria de la Consolacion. The third was the brigantine San Cristobal. Brigantines were smaller and could go closer to shore than the caravels could.Caravels of that time were of two forms. The older style was 'lanteen' rigged, meaning it carried two triangular sails in a form adapted from qarib ships used by Muslim explorers, and a newer square-rigged style called 'caravela redonda' by the Portuguese, in the Iberian (Spanish) style. Some caravels could mount either kind of sail, or both at once, square sails above and triangular ones below, fore, and aft.One existing drawing (see link below) shows that the Santiago and the Santa Maria de la Consolacion were of this newer, square-rigged type, perhaps with square sails at topmast and lanteen sails below.A caravela redonda like the Santiago might be as much as 30 meters long, carry three or four masts (the drawing seems to indicate three masts) and a few cannon.These caravels had no forecastle (the raised section on the front of the ship) and a shorter sterncastle (the reaised section to the rear of the ship) than the earlier 'carrick' design. This made them handle much better at sea.this is a gay answer!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

a square go to a local gym and look at their tramps. they have square ones a square one because the circle ones give you less room to do flips, so if you want to do a roundoff backhandspring on a circle one you'll probably hit the nets or go flying off the side (depending) if you look at the ones in the gymnastic places they're all square.
The triangular one is called a Balalaika. There are several rounded ones by different names.
Five. Two triangular ones (base and top) and three rectangular ones.
In math terms, a pyramid could have a square base, triangular base or another shape. The Egyptian pyramids (and Aztec ones) had a square base. So they had 8 edges (for on the base and 4 rising to the top) and 5 faces (4 facing up and the base).
Massive wooden ones with sails, but his most famous was called 'The Golden Hind'
