Request for improvement[edit]
Figure 3 should be improved. In the projection, the left edge of the purple part of the plane intersecting the cone accidentally passes through the apex of the cone. That gives the wrong impression that the plane passes through the apex. But that is actually not true. --BurghardRichter (talk) 11:13, 30 August 2023 (UTC)
