Source sentences:
text: An octahedron has eight faces (triangles), 12 edges, and six vertices; at each vertex four edges meet.
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: One face is a heptagon (usually regular), and the remaining seven faces are triangles (usually isosceles).
text: in the case of the regular octahedron, these faces are triangles.
text: One face is a heptagon (usually regular), and the remaining seven faces are triangles (usually isosceles).
text: One face is a heptagon (usually regular), and the remaining seven faces are triangles (usually isosceles).
text: The faces can be triangles, quadrilaterals, pentagons, hexagons or heptagons.
text: The faces can be triangles, quadrilaterals, pentagons, hexagons or heptagons.
text: Therefore, the faces can only be triangles, squares, or pentagons, so 3 ≤ m ≤ 5.
text: A regular octahedron has eight congruent polygons for faces (in this case, the faces are all triangles).
text: The faces can be triangles (3 sides), squares (4 sides), etc.
