Answer 1

Answer: 

b. The supplements of congruent angles are congruent

Explanation:

Note that $\angle TKL$ is a supplement of $\angle 3$ and $\angle TLK$ is a supplement of $\angle 4$. 

Since $\angle 3 \cong \angle 4$, $\angle TKL \cong \angle TLK$ because the supplement of the congruent angles are congruent.
