If your polygon is convex, take any point in the interior of the polygon, e.g. the average of all the vertices. Then you can compute the angle of each vertex to the center point, and sort according to the computed angles. This will work for any point inside the polygon. Note you will get a circular ordering.A,J(B) = B,J(C) = C. We claim that any isometry J fixing three non-colinear points A,B,C is the identity, and thus F = G. To justify the claim, note that a point P and and its image P′ = J(P) have the same distance to the fixed points A,B,C of the isometry J. If P 6= P′ then all points equidistant to them are situated on the line perpendic-

The general form of a pointer variable declaration is −. type *var-name; Here, type is the pointer's base type; it must be a valid C data type and var-name is the name of the pointer variable. The asterisk * used to declare a pointer is the same asterisk used for multiplication. However, in this statement the asterisk is being used to ...
