How can I prove that there are only seven unique geometric frieze patterns? Christina 

Hi Christina, If you classify frieze patterns by the amount of symmetry they have then you find seven distinct classification groups. You can find a proof of this in a note in the Math Central Resource Room titled Friezing at Washington State University. You can also find this article and another on frieze patterns by going to Math Central and searching in the Resource Room section for the word frieze. Penny
