This is a visualization of the proof that a triangle's angles sum to 180 degrees. Technical note: the key assumption is there is exactly 1 parallel to the right side passing through the left point. This is the parallel postulate of plane geometry (the standard one we learn in grade school). There are other types of geometries where triangle angles sum to more or less than 180 degrees (in hyperb...

It's so good
