Gary is using an indirect method to prove that segment DE is not parallel to segment BC in the triangle ABC shown.

He starts with the assumption that segment DE is parallel to segment BC.

Which inequality will he use to contradict the assumption?

4:10 ≠ 6:14

4:6 ≠ 6:14

4:10 ≠ 6:8

4:14 ≠ 6:10

amistre64 · Answer

the proportion of sides ..... in some fashion or another

4:6  is to (4+6):(6+8)  seems reasonable to me

amistre64 · Answer

this could be written a few ways

4:6 = 10:14
4:10 = 6:14
14:6 = 10:4

etc ....
