1. The problem statement, all variables and given/known data The problem involves drawing a particular set of lines and analysing anything of interest. The steps are as follows: : Begin with a hexagon with standard notation. : Draw a line (T) that passes through point B and which is parallel to AC. : Produce the lines AD and EC, remember to jot X at the intersection point. : Create line NX, with N on line (T) and NX is right angles to T. : Produce a circle with XB as the diameter. 3. The attempt at a solution I have attached a copy of my drawing, it doesn't have the construction lines because it is only rough, i'm firstly interested to see if I have the general idea. Gary.
