There are other ways that work well, too. I've had pretty good luck with the Easy Angle ruler, but still go back to the old favorite 2 square method.
This is the way I do mine too. My avatar is a quilt made with half square triangles. I'd rather trim and have them come out perfectly and the points match than trying to get them square to begin with.
