This makes tree rotations useful for rebalancing a tree. Consider the terminology of Root for the parent node of the subtrees to rotate, Pivot for the node which will become the new parent node, RS for the side of rotation and OS for the opposite side of rotation. For the root Q in the diagram above, RS is C and OS is P. Using these terms, the ...
The flip graphs of a pentagon and a hexagon, corresponding to rotations of three-node and four-node binary trees. Given a family of triangulations of some geometric object, a flip is an operation that transforms one triangulation to another by removing an edge between two triangles and adding the opposite diagonal to the resulting quadrilateral.
In a binary search tree, a right rotation is the movement of a node, X, down to the right.This rotation assumes that X has a left child (or subtree). X's left child, R, becomes X's parent node and R's right child becomes X's new left child.
Republican Senator Markwayne Mullin said on Monday that Robert F. Kennedy Jr., President-elect Donald Trump's pick for health secretary and a vaccine skeptic, told him he supports polio vaccination.

The rotation has two angles of rotation, one for each plane of rotation, through which points in the planes rotate. If these are ω 1 and ω 2 then all points not in the planes rotate through an angle between ω 1 and ω 2. Rotations in four dimensions about a fixed point have six degrees of freedom.
