Dodecagon has how many sides?

• A. 9
• B. 12
• C. 6
• D. 15

Answer: (B)

Polygon names encode the number of sides using Greek prefixes. In this case, dodeca- means twelve and -gon means a polygon or corner, so a dodecagon has twelve sides. That naming pattern helps you recognize that it’s twelve, not nine or six or fifteen, by simply parsing the prefix.
