Connect the 2 adjacent points respectively getting 6 triangles. One of this triangles (lets say XDE) must have an angle of at most 60° at X. This means the side DE can’t be larger than both sides XD and XE. Since there are no sides equal in length it must be shorter than one of the sides XD or XE. Contradiction.
