Adjancent Non-Supplementary Angles

Photograph by: Cece

This is a image is a picture of the the Pyramid in the Louvre looking up  from inside the visitor center in the Louvre. This picture was taken in March 2012 in the Louvre, Paris, France. Adjacent non-supplementary are angles that have a common vertex and side, but don't add up to 180 degrees. The red angle in this picture shares a side and vertex with the purple angle. Even though the angles appear to make a line, they actually don't form a straight line. This pyramid is used to look pretty for photographers, be a roof for the visitor center, and to draw even more attention to the world-famous museum.
