unit-distance

A generalized Petersen graph is a graph with $2n$ vertices, where each vertex has degree 3 and there are $3n$ edges.  A unit-distance graph is a graph with every edge of 1 unit  length.  We study the geometric transformation of a generalized Petersen graph into a generalized Petersen unit-distance graph and the rotation angles of the $n$-pointed star of the generalized Petersen unit-distance graph.  Then, we obtain the properties of the generalized Petersen unit-distance graph and the rotation angles of the $n$-pointed star of the generalized Petersen unit-distance grap
