In triangle \( \triangle LMN \), since it is isosceles with \( \angle M \cong \angle L \) and \( m\angle L = 36^\circ \), we have:
\[
m\angle M = m\angle L = 36^\circ
\]
Next, we use the fact that the sum of the angles in a triangle is \( 180^\circ \):
\[
m\angle L + m\angle M + m\angle N = 180^\circ
\]
Substituting the known values:
\[
36^\circ + 36^\circ + m\angle N = 180^\circ
\]
This simplifies to:
\[
72^\circ + m\angle N = 180^\circ
\]
To find \( m\angle N \), we subtract \( 72^\circ \) from \( 180^\circ \):
\[
m\angle N = 180^\circ - 72^\circ = 108^\circ
\]
Thus, the measures of the angles are:
\[
m\angle M = 36^\circ \quad \text{and} \quad m\angle N = 108^\circ
\]
\[
m\angle M = m\angle L = 36^\circ
\]
