question
△ckm can be mapped onto △rnl by
a reflection. if m∠c = 120°, find m∠n.
can
cannot
m∠n be determined.

Explanation:

Step1: Analyze the reflection mapping

Since \(\triangle CKM\) is mapped onto \(\triangle RNL\) by a reflection, the two triangles are congruent. In congruent triangles, corresponding angles are equal. But we are given \(m\angle C = 120^{\circ}\), and we need to find \(m\angle N\). There is no information given about the correspondence of \(\angle C\) and \(\angle N\) (i.e., we don't know if they are corresponding angles in the congruent triangles).

Answer:

cannot
