In triangle abc shown below, side ab is 6 and side ac is 4: triangle abc with segment joining point d on segment ab and point e on segment ac. which statement is needed to prove that segment de is parallel to segment bc and half its length?

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
