a square but once and a while it might be a triangle. It can be any shape you wish and it will be appropriately called either a square pyramid or a triangular, or hexagonal or rectangular or pentagonal pyramid etc etc. If the base is an equilateral triangle and its 3 faces are also equilateral triangles, it has a special name. It is called a Tetrahedron. An Oblique Pyramid is the name given to it if the 'apex' (the point at the top') is not directly and vertically above the centre of it's base. A pyramid which has portion of it 'sliced off' in it's upper portion , is called a Truncated Pyramid. If you have a cooking type pie dish with sloping sides, and turn it upside down, it will have a shape which is called a 'Truncated circular Pyramid'.
the shape of the base of a rectangular pyramid is a rectangle.
If it is a pyramid, then the base shape is a SQURE. If it is a tetrahedron, then the base shape is a triangle.
The bottom line of a shape is the base of the shape. For example, the bottom line of a pyramid is the base of the pyramid.
the base of a triangular pyramid is triangle
the base of a triangular pyramid is triangle
depends on what kind of pyramid it is
A pyramid (3D)! Some examples: - triangular base pyramid - square base pyramid - rectangular base pyramid - cone
The hexagon is the base.
A square pyramid is a pyramid whose base is in the shape of a square.
The base
It will be a square shape if it is a squared based pyramid
No, the base of a pyramid must be a 2-dimensional shape so no polyhedron can be its base.
