To start this creation I drew a line segment using the line segment button. I then used the point button to place point C on the line. I then used the compass button to draw a circle with the radius being the length of CB. I then marked the point of intersection with the intersection button. I then added point F to the line in between line CB. I then took the compass and drew a circle with the radius of DF, with D as the center. I then created another circle using the compass button with the radius of DF but B as the center. I then used the intersection button to find the point of intersection of circle D and circle B. Then using the line segment button I drew a line. Now I have my perpendicular lines
