Applet 9.1 : Isometrics of R2

    A linear map is an isometric means following :

  1.    T takes collinear points to collinear points, i.e. images of straight lines are straight lines
  2.    T preserves division-ratios
  3.    T  preserves distances

     The following applet describes all the isometrics of . To use applet proceed as follows :

  • Click at some points on the left panel to form a polygon
  • Choose a transformation
  • See the image in the right panel
