Cut the verteces.
Now place these verteces in such a way that they form a protractor shaped thing now the line at the bottom is a straight line AND wellaH!!! here we are with a perfect 180 deg.

Cut yourself a triangle out of paper. Rip the three corners off. Lay the corners together and they'll make a straight line. There are 180 degrees in a straight line, so the sum of the angles must also be 180 degrees.

Construct a triangle.
Cut it out.
Mark a dot on each vertex (so you know which ones you're interested in)
Cut each triangle into 3 pieces so that each vertex is on its own piece.
Paste the three vertices onto the straight edge of another sheet of paper.
Repeat until convinced.

I don't think you can. 180 is an artificial number, half of the degrees in a circle. The relations work, but the numbers themselves mean nothing.
