What is a 3D shape that is a tetrahedron?
Well, a tetrahedron has four sides. A regular tetrahedron is a triangular pyramid.
Is there a difference between a regular tetrahedron and a non-regular tetrahedron?
Yes. A tetrahedron is a closed 3-d shape with 4 triangular faces. In a regular polygon, each of these is an equilateral triangle.

Is a triangular pyramid a regular polyhedron?
A triangular based based pyramid is a TETRAHEDRON. It becomes a regular tetrahedron if the four triangles, that make up its shape, are REGULAR, that is they are all the same size by area and shape; that is they are congruent. The word 'polyhedron' means a solid shape of any number of sides.

A regular tetrahedron. octahedron, dodecahedron.
What shape has 4 faces which are congrugent triangles?
A four faced figure is a tetrahedron. If they are all congruent triangles, they are all equilateral triangles and it is a regular tetrahedron - one of the 5 Platonic Solids.
A shape that has triangular faces?
There are many possible shapes. The regular ones amongst them are the tetrahedron, the octahedron and the icosahedron.
What 3D shape has straight edges and no faces with a right angle?
A regular tetrahedron (an equilateral triangular pyramid).
How many internal diagonals are there in a regular tetrahedron?
zero, for any tetrahedron, not just regular
What is a 4 faced 3D shape?
tetrahedron is a 4 faced 3d shape.
Which shape has triangular faces?
There are an infinite number of possible answers. Tetrahedron. octahedron and icosahedron are the regular ones amongst them.
