Question

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

Answer 1

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

Which inequality will he use to contradict the assumption?

5:3 ≠ 6:10

5:8 ≠ 6:4

5:8 ≠ 6:10

5:3 ≠ 5:6

Answer 2

using similar triangle concept,in triangle ABC and ADE,it should be 5:(5+3)!=6:(6+4)....
