Question

what additional information is needed to prove that the triangles are congruent using the asa congruence theorem?
options:
$overline{nl} cong overline{mp}$
$overline{nk} cong overline{mq}$
$angle n cong angle m$
$angle l cong angle p$

Explanation:

To prove triangles congruent by ASA (Angle - Side - Angle), we need two angles and the included side to be congruent. From the diagram, we know that $\angle K=\angle Q = 90^{\circ}$ and $LK = QP$ (marked as equal). We already have one angle (the right angle) and one side. For ASA, we need the included angle between the side and another angle to be congruent. The angle $\angle L$ and $\angle P$ are the other non - right angles. If $\angle L\cong\angle P$, then with $LK = QP$ and $\angle K=\angle Q$, we can apply ASA. Let's analyze the other options:

• Option 1: $\overline{NL}\cong\overline{MP}$: This is a side that is not the included side for the angles we have, so it doesn't help with ASA.
• Option 2: $\overline{NK}\cong\overline{MQ}$: This is also not the included side for the angles related to ASA.
• Option 3: $\angle N\cong\angle M$: These angles are not the angles that would form the ASA with the given right angles and the equal side.

Answer:

$\boldsymbol{\angle L\cong\angle P}$ (the option with the text "$\angle L\cong\angle P$")
