"WebIt is easy to check that a single rotation preserves the ordering requirement for a binary search tree. For example, based on the position of subtree B in the left-hand tree, all values in B must be < x and > y.That is just what is required of B in the right-hand tree.. Notice that the single rotaton has moved tree B from the left-hand side to the right-hand side. " - Binary search tree rotation
