How can we prove there are 180 degrees in a triangle (HINT: remember the cut & paste activity with the triangle corners)

If you cut all the corners off a triangle and put them together, you get a straight line. We know that there are 180 degrees in a straight line, so there must also be 180 degrees in a triangle.
