Geometric graphs | Intersection classes of graphs
In graph theory, a circular-arc graph is the intersection graph of a set of arcs on the circle. It has one vertex for each arc in the set, and an edge between every pair of vertices corresponding to arcs that intersect. Formally, let be a set of arcs. Then the corresponding circular-arc graph is G = (V, E) where and A family of arcs that corresponds to G is called an arc model. (Wikipedia).
What is the formula to determine the length of an arc
Learn how to solve problems with arcs of a circle. An arc is a curve made by two points on the circumference of a circle. The measure of an arc corresponds to the central angle made by the two radii from the center of the circle to the endpoints of the arc. The measure of the angle on a c
