Three segments are drawn from opposite corners of a hexagon to form six triangles. These segments bisect each other at point A. Are all the six triangles that are formed using point A and one side of each of hexagon equilateral.

1)All six sides of the hexagon are of the same length.
2) The three segments between the opposite corners are the same length.

[spoiler]OA = C. Can someone please tell why not A or B alone not sufficient ?[/spoiler]
