<span>The answer would be:
B. ∠DEC is an exterior angle.
C. ∠ABE and ∠EBC are supplementary angles.
</span>
∠BEC is an interior angle as it was located inside the triangle. ∠DEC is an exterior angle since it was located outside the triangle. ∠ABE and ∠EBC are supplementary angles because their sum is 180. ∠BCF is not making a supplementary angle with ∠BEC.<span>
∠BEC and </span>∠EBC is a remote interior angle to exterior ∠BCF. I think it should be false since the option only put one of the remote interior angles.
