@science0229 those aren't lines of symmetry. Imagine folding it over those lines... it's not symmetric.

Parallelograms can have zero lines of symmetry.

agent0smith · Answer

@KelliRovesSkittles the minimum is zero.

science0229 · Answer

No parallelogram has zero lines of symmetry.
If there is one, can you draw one for me?

agent0smith · Answer

@science0229 any regular parallelogram (not a square/rhombus/rectangle etc) has zero lines of symmetry... such as the one you drew.

agent0smith · Answer

Try drawing a parallelogram and folding it over, it'll never fold perfectly onto itself unless it's one of the special cases.

science0229 · Answer

If I were to draw a precise parallelogram that is not special case and draw the 2 lines of symmetry that goes through the midpoints of each side and parallel to each side, it would fold perfectly.

lol okay. You do that then and prove everyone wrong... http://hotmath.com/hotmath_help/topics/line-symmetry.html http://mathcentral.uregina.ca/QQ/database/QQ.09.08/h/anisha1.html http://www.ask.com/question/how-many-lines-of-symmetry-does-a-parallelogram-have

oops.....

@KelliRovesSkittles. I'm really sorry. Listen to agent0smith. I also apologize to agent0smith.
I must be getting tired. I gotta go to sleep...

P.S. please remove my medal. agent0smith deserves one, though...

I'll give you a medal for realizing your mistake :P
