I have to use a # line to find the ratio of the segment lengths.
BD:CF
point B is on the # 2. point D is on the # 9. point C is on the # 6, and point F is on the # 13.
(How did they arrive with a answer of 1\1?)
From B to D is 2 to 9, or 7.
From C to F is 6 to 13, or 7.
The ratio is 7/7, which is equal to 1/1.

Measure and add up the angles of each quadrilateral. We can inductively conclude that: the sum of the angles of a quadrilateral is 360 degrees
