Question

what other information do you need in order to prove the triangles congruent using the sas congruence postulate?
o ∠l≅∠h
o (overline{lm}congoverline{hm},overline{mn}congoverline{mj})
o (overline{mn}congoverline{mj})
o <n≅ <j

Explanation:

Step1: Recall SAS Congruence Postulate

The SAS (Side - Angle - Side) Congruence Postulate states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.

Step2: Analyze given figure

We need two pairs of congruent sides and the included angles between them to be congruent. From the figure, we may assume some side - congruences are already given (the marked segments). We need the included angle between the sides to be congruent.

Step3: Identify the correct option

The option that provides the information about the included angle being congruent is $\angle L\cong\angle H$.

Answer:

$\angle L\cong\angle H$
