Math Mind Bender

Despite Maths and Stats being my first love, I have scarcely written any post on mathematical wonders or puzzles. Here's a very simple and small puzzle. We all know that the sum of the internal angles in a triangle is 180 degree. But there are two cases when the sum can be more than 180 or less than 180. Can you tell how that is possible. Yes! THAT IS possible! Just "bend your mind" Answer to this puzzle on next Monday!
