Only those who have passed high school geometry (or equivalent) should post....really folks, what IS a triangle? Gotta have 3 and only 3 sides, any angles possible, must equal 180 (by definition). But we could make this thread more specific....only equilateral triangles? acute? Isosceles? obtuse? right? scalene? Any or all of the above...only. Or a new thread: 4 sides panties? Pentagons? Octagons?
