4. 1 at the bottom and 3 joininq on to it. Simples.
It makes a Triangular Pyramid.
If you arrange them in the form of a tetrahedron - a triangular pyramid.
It will look like a 2D equilateral triangle if it is a triangular based pyramid which is called a tetrahedron.
They are both 3d and they both form triangles on the sides to come up and make a point
Think in 3-dimensions and make a tetrahedron (a triangular pyramid).
A tetrahedron or triangular pyramid.
It makes a Triangular Pyramid.
make a square base with the four sider make 4 triangles that are on eachside
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.

Sort of depends on how the two triangles are beforehand. One nice way to make four equilateral triangles from six matchsticks is to make a tetrahedron (a triangular pyramid).
Yes. They have perpendicular bisectors in the four triangles that make up four of the five sides of a square-based pyramid
Because a triangular pyramid has 6 edges
you can make a square based pyramid using 4 triangles and a 1 square
