A triangular pyramid is a 3-dimensional geometric figure that has 5 sides. Four triangle shaped sides that are connected to one square shaped based. * * * * * If it has a square shaped base then it is a square based pyramid! A triangular pyramid has 4 faces. It is also called a tetrahedron.

A Triangular Based Pyramid is a Pyramid which has triangular faces and a triangular base. It has 4 vertices, 6 sides, and 4 faces. A Triangular Based Pyramid is also called a Tetrahedron

five A triangular based prism has 5 A triangular based pyramid has 4 and there is no such thing as a triangular based prism pyramid - unless you mean a truncated pyramid (or a frustum) which is essentially a prism.

A triangular based pyramid would have 4 corners; three for the triangular base and one for the peak. A pyramid has twice as many edges as sides in its base; thus a triangular pyramid has 2 × 3 = 6 edges. A triangular based pyramid is called a tetrahedron.

No, it has five plus the bottom :D * * * * * The previous answer is incorrect: a pyramid with 5 faces plus the bottom would be a pentagon based pyramid! A triangular based pyramid, or tetrahedron, DOES have 4 triangular faces.

There are several options: A hexagon based pyramid A pentagonal based bipyramid A triangular based prism + quadrilateral pyramid (attached along a quadrilateral face) A triangular pyramid on a triangular prism (attached along a triangular face)
