# About '*Where is the Pentagon?*'

I know some people has no idea

**where is the Pentagon**. Notice: not '

*pentagon*'; '

**Pentagon**'. Capital letter 'p'.

If you think about the pentagon -- it's (in geometry, of course) a kind of polygon. Its name comes from the Greek words 'πέντε' (pente) and 'γωνία' (gonia), meaning 'five' ('5') and 'angle'). It is any five-sided polygon (or 5-gon). And the sum of the internal angles in a simple pentagon is 540°. (Source:
