Six triangles.
A polyhedron made from four triangles that are not equal is called a tetrahedron. Specifically, if the triangles are not congruent, it is referred to as an irregular tetrahedron. Tetrahedra are three-dimensional shapes with four triangular faces, six edges, and four vertices.
A triangle has three sides, so six triangles have 6 * 3 = 18 sides altogether.
