An Autograph Activity to demonstrate why the angles in a triangle add up to 180 degrees. The interesting thing about this activity is that it has no numbers! So really it is a demonstration that the angles in a triangle when put together form a straight line.
This activity was inspired by the awesome Oliver Byrne's 'The Elements of Euclid'. Mathematics is not just about numbers, using colours in this example hopefully demonstrates that.
