[list=1][*]Draw a ray [icon]/images/ggb/toolbar/mode_ray.png[/icon] beginning at the center through each vertex of the figure.[/*][*]Dilate each vertex along the appropriate ray by the scale factor. For example for a scale factor r = 1/2, find the midpoint [icon]/images/ggb/toolbar/mode_mirroratpoint.png[/icon] between the center and each vertex.[/*][*]Use the segment tool [icon]/images/ggb/toolbar/mode_segment.png[/icon] to join the vertices in the way they are joined in the original figure.[br][/*][/list]
