None
Not as a regular 5 sided pentagon but quite possible as an irregular pentagon.

yes they do. they have a perpendicular line. * * * * * No, a pentagon, as in a regular polygon does not have perpendicular lines. An irregular pentagon could, and you can always add perpendicular lines to any shape.
