Click to expand... This is a standard corollary of parallel theorems. It should be in your text-book - tell us what you found. Otherwise, do a google search - you might find it all worked out. Otherwise, start sketching a parallelogram and show that for the given condition - the adjacent sides will be congruent (condition for a rhombus). If you are still stuck, write showing (describing) your work - and exactly where you are stuck.
