the smaller triangles within the triangles are different sizes, so by moving them you changed the dimentions within the triangle (the completed size). The only thing about the triangle (big one) is the hypotenuse angle is the same in the two small triangles, and the completed large triangle. so that the length of the base should equal the angle 30 degrees (it's a 30,60, 90 triangle) where the height will be the same and the hypotenuse will equal twice the height. blah blah blah I'm babbling.
