Source sentences:
text: One face is a heptagon (usually regular), and the remaining seven faces are triangles (usually isosceles).
text: Regular polygons of six or more sides have only angles of 120° or more, so the common face must be the triangle, square, or pentagon.
text: Therefore, the faces can only be triangles, squares, or pentagons, so 3 ≤ m ≤ 5.
