In the literature, there are several graphs related to a finite group $G$. Two of them are the character degree graph, denoted by $\Delta (G)$, and the prime graph, $\Gamma (G)$. In this paper we classify all finite groups whose character degree graphs are disconnected and coincide with their prime graphs. As a corollary, we find all finite groups whose character degree graphs are square and coincide with their prime graphs.
