It is interesting the different interpretations of triangles that are seen on this forum. You may not have seen one of these play out because maybe they are not triangles?

IMHO . . . A triangle would wave up and down (roughly as per the pink line) and not have so much 'fresh air' within the triangle (e.g. yellow highlighted area). In addition, a well behaved triangle would break out somewhere before reaching the pointy end. Remember, it's just an opinion.
