That is taken out of context. First, it is a resource for teacher, explaining what reasoning student might make. The paragraph you quoted from starts with: "Students may also reason that ... ", which doesn't mean it is a correct reason, or by any means a definition. Aside from that, the paragraph is talking about an hypotetical case in which a triangle has no interior, and one angle is 180 degrees and the other two are 0 degrees, which is wrong per definition, as the sum of the interior angles must be greater than 180 degrees. -- Marcelo - http://maps.forum.nu -- --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API" group.
