1) Make perpendicular lines(elbows at 0 points)
2) then put the term needle at point 0 and open the term with the size up( not too big)
3)turn the term. so that the bow we make cuts a line that is perpendicular to each other(in the picture shown on a red bow intersecting points A and B)
4)put, needle at point A them turn the run
5)put the term at point B, then rotate term until it intersects with the round term centered at point A
6)in the picture is a green bow
7) pull the intersection line to point 0(elbow point) so that an angle of 45 degress is formed
