    Not knowing how to do your homework IS NOT urgent.

    You need a carpenters square!

    on the same edge, set one side at 6" and the other at 12"! This will give you all of your lines for either vertical or horizontal.

      The assignment was to layout the cuts, not structural calculations.

    Any carpentry manual should give you setting out for these.
