Rooted and unrooted trees QuickTimeª and a TIFF (Uncompressed) decompressor are needed to see this picture. “Degree” of a node = the number of neighbors of that node. In a “binary” tree, all nodes have degree 1 or 3, except the root which has degree 2. (i.e. each node has 0 or 2 children). A binary tree with N leaf nodes has N-1 internal nodes (c.f. table-tennis tournament. ..)
