The 45, 45, 90 degree triangle is my favorite one-point perspective drawing tool. The 90 degree or right angle sides of the triangle are for drawing horizontal and vertical lines. The corner of the triangle in the lower right-hand corner of the page is the 90 degree or right angle side of the triangle.

Click on a 90 degree or right angle.
