The planar figure of two triangles being in perspective position is associated with a theorem of Desargues. which is responsible for the fact that the coordinate set of the plane is a field. This well-known theorem of Desargues allows the obvious interpretation in space of a three-sided pyramid. which is intersected by two planes. https://www.bekindtopets.com/save-now-2023-Head-Total-Joy-SW-SLR-Pro-Skis-w-Joy-11-GW-Bindings-mega-pick/
