Welcome to UNIZOR.COM http://www.unizor.com.
Imagine an ordered set of N segments arranged in a chain such that "right" endpoint of the first segment is connected to the "left" endpoint of the second segment, the "right" endpoint of the second segment is connected to the "left" endpoint of the third segment, the "right" endpoint of the third segment is connected to the "left" endpoint of the fourth segment etc. The "right" endpoint of the Nth segment is connected to the "left" endpoint of the 1st segment thus closing the chain.
The figure we obtained is called polygon.
