Two-point perspective has one set of lines parallel to the picture plane and two sets oblique to it. Parallel lines oblique to the picture plane converge to a vanishing point, which means that this set-up will require two vanishing points. Walls in 2-point perspective, converging toward two vanishing points.

Given: A Î´ ABC and a line intersecting AB in D and AC in E, such that AD / DB = AE / EC. Prove that: DE || BC Let DE is not parallel to BC.
