Im not 100% sure though regarding the emf polygon ,i think they are used to derive the distribution factor.

Distribution factor ,is the measure of resultant emf of a winding in comparison to a concentrated wiring.

The distribution factor or breadth factor is defined as the ratio of the actual voltage
obtained to the possible voltage if all the coils of a polar group were concentrated in a single
slot.
