I am not sure what you are asking. Do you mean Quarter Square Triangles? Yes just lay two Half Square Triangles on top of each other, draw a line diagonally, sew 1/4 inch to each side of the line and then cut on the line. Let me see if I can find a link.
This one is different but this works too.

I hope one of these links works for you. If not maybe you could try and reword your question?
