A polyhedron must meet three conditions in order to beregular:
All of the faces are regular polygons;
All of the faces are congruent (identical);
All of the vertex points/arrangements are congruent(identical).
Try to find three nonregular polyhedra, each of which violates adifferent one of these conditions. In other words, one of themshould meet (1) and (2) but not (3); one should meet (1) and (3),but not (2); one should meet (2) and (3) but not (1). Describe eachpolyhedron using words:
number of faces and the polygons forming the faces
number of vertices and their vertex arrangements
number of edges
** Make sure to state which condition is being violated in eachcase
