Pentagons Within a Lotus Chandelier

I saw this giant lotus chandelier, probably about 20 feet tall, in a shop in Chinatown, San Francisco.

From the naked eye I thought I found a regular pentagon within the body of the chandelier, but I was rather disappointed to find that it is only a pentagon (not regular). All the side lengths are different, but the angles add up to 540 degrees. Since the differences in length are so minute, I can see why I assumed it a regular pentagon.  (~LU2)
