I first drew segment AC and drew a circle centered around B. Then I put G and K on the circle, connected them and drew triangle GFB. After that I drew segment HI and added points K,L, and J on the segment. I then drew 2 circles centered on K and J. JG and KF are equal because they are both the radius and intersect at the endpoints of the radius of circle J and K. KJ is parallel to FG because they are both perpendicular to AC.
