Take a square fold it in half by bringing two opposite corners together. Now you have a right angled triangle with the closed edge being the hypotenuse. Make an angle bisector by bringing one free edge down onto the hypotenuse and make a small pinch mark on the side that doesn't meet the corner. Unfold the last fold and fold the corner you folded through to the point just created. Finish like usual.
