WebAn intuitive way to show this is to cut out a triangle from paper. Rip off the corners and put them together with the points of the triangle touching. If you make them all adjacent to one another, they will form 180 degrees. To prove this, let's say we have a triangle ABC. We could create a line parallel to BC through point A. portable outdoor landscape flood light
