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.
1 Corresponding Angles Postulate If two parallel lines are cut by transversal, then the pairs of corresponding angles are congruent. ( 2 page 135). 3  Corresponding Angle Converse If two lines are cut by a transversal so that corresponding angles are congruent, then the lines are parallel.
