Question

(b) not necessarily congruent congruent: △mno ≅ △ by the

Explanation:

Step1: Identify the corresponding parts

In \(\triangle MNO\) and \(\triangle PRQ\), we have \(MN = PR\) (marked with one tick), \(\angle N=\angle P\) (marked with one arc), \(\angle O=\angle R\) (marked with two arcs).

Step2: Apply the AAS (Angle - Angle - Side) congruence criterion

The AAS congruence criterion states that if two angles and a non - included side of one triangle are equal to two angles and the corresponding non - included side of another triangle, then the two triangles are congruent.

Answer:

Congruent: \(\triangle MNO\cong\triangle PRQ\) by the AAS (Angle - Angle - Side) congruence criterion.
