#### Abstract

In this paper we prove a rigidity result for the equality case of the Penrose inequality on \$3\$-dimensional asymptotically flat manifolds with nonnegative scalar curvature and corners. Our result also has deep connections with the equality cases of Theorem 1 in \cite{Miao2} and Theorem 1.1 in \cite{LM}.
