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.
four sides and a base
A triangular based pyramid has 4 sides. 3 triangle sides and 1 Square base
it is a 3 dimentional triangle ... it can be a pyramid with 5 sides ... or one with four sides
Square Pyramid has a square base and 4 triangular sides. Triangular Pyramid has a triangle base and 3 triangular sides.
A square pyramid has 1 square base and 4 triangle-shaped sides.
I presume the question is meant to be: How many sides does a pyramid have? The answer is 4 or more. A pyramid has a polygonal base where the polygon can have 3 or more sides. Corresponding to each of these sides there will be a triangle rising to the apex of the pyramid. In all, a pyramid whose base is a polygon with n sides will have n+1 faces (sides).
With a triangle base there are four sides including the base
No. A triangle can be a two-dimensional object whereas a pyramid must be three-dimensional (with sides that are sloped).
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.
4
4 faces. The number of faces on a pyramid is one more than the number of sides of the base. A triangle has 3 sides, therefore a triangular pyramid has 3 +1 = 4 faces.
