Question

GEOMETRY PLEASE HELP

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

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

Which inequality will he use to contradict the assumption?

A.) 4:10 ≠ 6:14
B.) 4:6 ≠ 6:14
C.) 4:10 ≠ 6:8
D.) 4:14 ≠ 6:10

Answer 1

For DE to be parallel to BC, AD:AB must be equal to AE:AC. Here 4:10 ≠ 6:14
