Answer:
The reason for statement #7.
C) Converse of the same side consecutive angles theorem.
Step-by-step explanation:
For Parallel Lines:
Same side consecutive angles theorem
When the lines are parallel, the interior angles on the same side of the transversal are supplementary.
Here,
It is Converse Of above Statement
∠ 6 and ∠ 13 are supplementary
i.e
∠ 6 + ∠ 13 = 180°
Therefore the Reason is
C) Converse of the same side consecutive angles theorem.
That is If ∠ 6 and ∠ 13 are supplementary then the Lines are Parallel
i.e t₁ || t₂
