  2. I cant figure out how to include the pic of it

  3. just describe the picture, mentioning the lines and angles. For example

    Given lines l (AB) and m (CD), a transversal crosses them, intersecting

    line l at P
    line m at Q

    angle 1 is APQ

    Then we can reproduce your diagram.
