Eshaal is creating a model of a pyramid. The model created will need to be scaled up from the blueprint. triangle ACB, point D is on segment AC between points A and C, point E is on segment BC between points B and C

If segments DE and AB are parallel, which of the following expressions will help Eshaal determine the length of segment BC?

BC = CE
BC equals AC times CE all over CD
BC equals AC times DE all over CE
BC = AC
