Question

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

a. ∠n≅∠r and ∠l≅∠t are both needed because all three corresponding angles must be congruent to use sas.
b. ∠n≅∠r is needed because the congruent angles need to be included between two corresponding congruent sides.
c. ∠l≅∠t 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.

Explanation:

Answer:

B. \( \angle N\cong\angle R \) is needed because the congruent angles need to be included between two corresponding congruent sides.
