In graph theory, a graph is a pairwise compatibility graph (PCG) if there exists a tree and two non-negative real numbers such that each node of has a one-to-one mapping with a leaf node of such that two nodes and are adjacent in if and only if the distance between and are in the interval . The subclasses of PCG include graphs of at most seven vertices, cycles, forests, complete graphs, interval graphs and ladder graphs. However, there is a graph with eight vertices that is known not to be a PCG. (Wikipedia).

What are the Angle Relationships for Parallel Lines and a Transversal
π Learn about converse theorems of parallel lines and a transversal. Two lines are said to be parallel when they have the same slope and are drawn straight to each other such that they cannot meet. In geometry, parallel lines are identified by two arrow heads or two small lines indicated i
