Corresponding sides are sides that have the same relative position the same theyre playing the same role in each of the diagrams even if the diagrams are scaled versions of each other even if they are different sizes. These points share a common line of direction and this explains why stimulating them is perceived as arising from the same point in space. So for example if I clicked in the upper left 00 in the rotated view it should correspond to 01280 in the original image.
Here Q and P are called as corresponding points on the auxiliary circle and the ellipse respectively.
The whole reason is to give you this appreciation that these are inverse functions of each other. I need help transforming a selected point in the Rotated View back to its corresponding point in the original Image. If you rotate 360 degrees either clockwise or counterclockwise maps an image to itself. For example Polygon 2 is a scaled copy of Polygon 1.
