Perspective drawings all have vanishing points. The more you have the more difficult the drawing gets. The term orthogonal lines are a mathematical term. in this case they are the lines that get farther away from us, and later meet. Now lets talk about the number of vanishing points. If you only have one, lines (orthogonal) will go to one point on the page. However, if you have more than one, that means there will be lines going everywhere. since the lines would go in all directions, it would be harder to draw.

This time, I included a YouTube video to substitute for the website. The video talks about the laws of perspective. As you look at the painting it shows you in the video, you can see where the vanishing points and the horizon line are. It talks about orthogonal lines, which are the lines that go across the paper or canvas meeting at the vanishing points. Although the lines are parallel in real life, in the picture, the lines meet at a certain point. As the lines get farther away, the lines get closer together, making it give off the effect of it looking three dimensional.
