Theory of the similarity solution of two-dimensional point vortices in an unbound-ed region is presented. To get the solution, the time dependence of the solution for allvortex positions are assumed to be the same. It is shown that the system either rotatesrigidly or collapses according to the initial position of vortices. Then numericalcalculations are made especially for the system of three vortices. It is found that therigid rotation corresponds to the regular triangle solution or the straight line solution,and that irrespective of the strengths of three vortices, the regular triangle solutionalways exists while the straight line solution is obtained by solving a certain cubicequation.
