It will look like a 2D equilateral triangle if it is a triangular based pyramid which is called a tetrahedron.
Because a triangular pyramid has 6 edges
pyramid
To make a triangular-based pyramid, you would need a total of 6 straws. This includes 3 straws for the triangular base and 3 additional straws connecting each vertex of the base to the apex of the pyramid. The straws form the edges of the pyramid, creating its structure.
Four triangular faces.
A pentagonal pyramid consists of a pentagonal base and five triangular faces that converge at a single apex. The pentagon serves as the base shape, while each of the triangles connects one side of the pentagon to the apex, creating the pyramid's three-dimensional structure. Thus, the two-dimensional shapes involved are the pentagon and the triangles.
octogons
They are. For all the material the use, you could make a really strong triangular pyramid.
Because a triangular pyramid has 6 edges
pyramid
A cube has 6 faces and a triangular pyramid has 5 faces. So a cube has 1 more face than a triangular prism. But a triangular pyramid has four faces. You make the call. That is correct: A triangular prism has five faces, and a cube has six faces, but a triangular pyramid has four faces.
A tetrahedron or triangular pyramid.
By bracing it with triangular shapes.
