Pappus' Sun

{{$t('general.by')}}

This sketch illustrates the Papus theoreme. In the blue frame, you can see 3 couples of parallele lines. This figure can be reshaped by right click and drag thanks to the red and yellow spheres. This figure is projected to the pink frame from the yellow sun at the top left corner point of view. The blue and pink frame can be oriented and moved thanks to the red spheres (at the corner of each frame): a right click generates a translation, a left click generates a rotation. Merci à Proscene pour ses bons services.
