Source sentences:
text: Similarly, a polyhedron is a solid that has only straight edges and flat faces (that is, faces that are polygons).
text: Edges are straight lines which serve as the junction of two faces.
text: The shadows of the polyhedron edges form a planar graph, embedded in such a way that the edges are straight line segments.
text: In geometry, a polyhedron is traditionally a three-dimensional shape that is made up of a finite number of polygonal faces which are parts of planes; the faces meet in pairs along edges which are straight-line segments, and the edges meet in points called vertices.
text: A geodesic polyhedron has straight edges and flat faces that approximate a sphere, but it can also be made as a spherical polyhedron (a tessellation on a sphere) with true geodesic curved edges on the surface of a sphere. and spherical triangle faces.
