Triangulation (geometry) | Binary trees | Reconfiguration
In discrete mathematics and theoretical computer science, the rotation distance between two binary trees with the same number of nodes is the minimum number of tree rotations needed to reconfigure one tree into another. Because of a combinatorial equivalence between binary trees and triangulations of convex polygons, rotation distance is equivalent to the for triangulations of convex polygons. Rotation distance was first defined by Karel ฤulรญk II and Derick Wood in 1982. Every two n-node binary trees have rotation distance at most 2n โ 6, and some pairs of trees have exactly this distance. The computational complexity of computing the rotation distance is unknown.

Determine the distance between two points on a coordinate axis
๐ Learn how to find the distance between two points. The distance between two points is the length of the line joining the two points in the coordinate plane. To find the distance between two points in the coordinate plane, we make use of the formula d = sqrt((x2 - x1)^2 + (y2 - y1)^2). ๐
