    @ze4life Please provide the diagram and instructions. This looks as if it might be a question about various quadrilaterals.

    The attached chart displays the theorems used to prove that a quadrilateral is a parallelogram. Please review them.

    @ze4life I'll help you get started by working the first two problems. ------------ 7) If one pair of opposite sides of a quadrilateral are both congruent and parallel, the quadrilateral is a parallelogram. |dw:1359783930539:dw|

    8) A quadrilateral with both pairs of opposite sides parallel is a parallelogram. You can just answer "Definition of parallelogram." |dw:1359784112088:dw| @ze4life If you post what you think are the reasons for problems 9 -11, I will check them for you.

    all of these are requirements for a parallelogram based on the definition of a parallelogram, in other words, it is defined to be the shape where all of these things hold true

    @ze4life Learn the Geometry theorems and you will be able to understand how to do the problems.
