Imagine a pyramid, with a triangle shaped base, with three sides coming up each of which is a triangle. That is a tetrahedron (4 sides, all the same side, with each one the shape of a triangle).

Mostly correct, but the four faces need not all be the same.
A tetrahedron is 3-dimensional and so it looks just like an ordinary tetrahedron.
It will look like a 2D equilateral triangle if it is a triangular based pyramid which is called a tetrahedron.
A tetrahedron must be plane faced and so, it is just an ordinary tetrahedron.
Well, a tetrahedron has four sides. A regular tetrahedron is a triangular pyramid.
A Tetrahedron. The most common form of a tetrahedron is called a regular tetrahedron, or a pyramid
A tetrahedron is 3-dimensional and so it looks just like an ordinary tetrahedron.
A silicon tetrahedron is a structure in which a silicon atom is covalently bonded to four other atoms, typically oxygen atoms. It forms a pyramid-like shape with one silicon atom in the center and four oxygen atoms at the corners. This structure is the building block of silicon-based minerals and materials.
In geometry, an octahedron is a polyhedron with eight sides. A regular octahedron is the dual polyhedron of a cube; It is a rectified tetrahedron.
A tetrahedron looks like a pyramid but instead of having a square base, it has a triangular base.
A pyramid with a triangle as base is considered as a tetrahedron. It is a three dimensional polyhedron with 4 equilateral triangles as its sides. If one would look at the word tetrahedron, it literally means "with four planes".
A tetrahedron.
I am not a tetrahedron!
It will look like a 2D equilateral triangle if it is a triangular based pyramid which is called a tetrahedron.
A tetrahedron has 4 faces but it doesn't look like a rectangle standing up. It is formed by 4 triangular faces.
A tetrahedron has 4 faces.
A tetrahedron must be plane faced and so, it is just an ordinary tetrahedron.
