Source sentences:
text: For example, with the icosahedron, each face is a triangle, and therefore p=3 and A = 60o.
text: An icosahedron is a 20-sided polyhedron with each face being a triangle.
text: As each face of the icosahedron is a triangle, we can choose to subdivide the triangle into smaller triangles.
text: Since there are 20 faces, and each face is a triangle
text: In semi-regular icosahedra (like in those pictures), the faces are most often all triangles.
text: One face is a heptagon (usually regular), and the remaining seven faces are triangles (usually isosceles).
text: Therefore, the faces can only be triangles, squares, or pentagons, so 3 ≤ m ≤ 5.
text: In fact, all the faces are triangles.
