Step1: Identify corresponding parts

In congruent - like triangles, match angles and sides.

Step2: Check angle - side - angle relationships

$\angle B$ in first triangle and $\angle M$ in second triangle are right - angles. Also, side lengths and other angles match in a way that $\angle B\cong\angle M$.
