It seems kind of confusing that the edges would be referred to as "top edge" or "left edge" because to me, that implies the existence of a "bottom edge" and "right edge" even though triangles only have three sides. Does this mean that sometimes a triangle might lack a top edge or a left edge?

I found the "Rasterization Rules" section of the following link (https://www.scratchapixel.com/lessons/3d-basic-rendering/rasterization-practical-implementation/rasterization-stage) will be helpful for further understanding Top edge and Left edge and how this setting can solve the issue of pixel center's overlapping with more than one triangle
