compare lengths of other sides between both the triangles

ganeshie8 (ganeshie8):

see any relation between the lengths of corresponding sides ?

OpenStudy (anonymous):

well..wouldnt BC and EF be congruent?

ganeshie8 (ganeshie8):

thats a good first guess, but no. are the sides AB and DE congruent ?

ganeshie8 (ganeshie8):

AB = 5 DE = 10 that means DE is exactly `twice` of AB, eh ?
