what other information, if any, do you need to prove the two triangles congruent by sas? explain.

choose the correct answer below.
a. $\overline{lt} \cong \overline{mq}$ and $\overline{gt} \cong \overline{nq}$ are both needed because all three corresponding sides must be congruent.
b. $\overline{lt} \cong \overline{mq}$ is needed because the congruent angles need to be included between two corresponding congruent sides.
c. $\overline{gt} \cong \overline{nq}$ is needed because the congruent angles need to be included between two corresponding congruent sides.
d. no additional information is needed to prove the triangles congruent by sas.

A. $\overline{LT} \cong \overline{MQ}$ and $\overline{GT} \cong \overline{NQ}$ are both needed because all three corresponding sides must be congruent.

B. $\overline{LT} \cong \overline{MQ}$ is needed because the congruent angles need to be included between two corresponding congruent sides.

C. $\overline{GT} \cong \overline{NQ}$ is needed because the congruent angles need to be included between two corresponding congruent sides.

D. No additional information is needed to prove the triangles congruent by SAS.
