tetrahedron
Are the triangles in a geodesic dome regular polygons?
Only if it is a regular tetrahedron, regular octahedron, or regular icosahedron. All other geodesics have isosceles triangle faces, not equilateral triangles.
What is a base figure for a triangular pyramid?
A triangular pyramid is usually called a tetrahedron; its base is an equilateral triangle, as are the other three of its sides. An Egyptian pyramid has a square base; the other four sides are isosceles triangles.
