A triangular based pyramid has 4 sides. 3 triangle sides and 1 Square base
four sides and a base
A square based pyramid.
A square pyramid has the base of a square,and sides of a triangle. While a triangle pyramid has the base and sides of a triangle.
It is not possible to answer the question without knowing if the pyramid is a triangle based, square based or other polygon based pyramid.
because the the sides of a based form a face of a pyramid
A pyramid has a based that is a polygon such as a triangle or rectangle. The other sides of a pyramid consist of triangles, which are usually the same size.
No. A triangular pyramid describes a triangle whose base is a triangle (not just the sides which define it as a pyramid), whereas a rectangular pyramid is one whose base is a rectangle. A triangle and a rectangle are not the same (a triangle is not a rectangle, and a rectangle is not a triangle), so it would be incorrect to refer to a triangle-based pyramid as a rectangle pyramid.
A pyramid can have an infinite number of sides other than two. If it has one (or an infinite number of) side(s), it is considered a cone. If it is, for example, a hexagonal pyramid, it will have six sides. A triangle-based pyramid has three sides. A square-based pyramid, commonly the structure used by ancient Egyptians, has four sides. There can be pentagonal pyramids, hexagonal pyramids and so on.
None. A triangle based pyramid is a 4-sided solid (a tetrahedron), and has no parallel sides.
