katrin2010 [14]

The information that would be sufficient to prove that both triangles are congruent by the SAS congruence theorem is: ∠E ≅ ∠N.

<h3>What is the Side-angle-side Congruence Theorem (SAS)?</h3>

When two sides and one included angle in a triangle is congruent to two corresponding sides and an included angle in another triangle, both triangles are congruent to each other by the SAS congruence theorem.

Thus:

ΔDEF and ΔMNO have:

Two pairs of congruent sides: DE ≅ MN and EF ≅ NO.

Therefore, the information that would be sufficient to prove that both triangles are congruent by the SAS congruence theorem is: ∠E ≅ ∠N.
