In this paper, we give a necessary and sufficient condition for a ć - joint B at σ = {u, v} in G to be an acyclic ć - joint and đ - joint at σ in Gσ when uv ∈ E(G) and uv ∉ E(G). Also we give a necessary and sufficient condition for a đ- joint B at σ in G to be an acyclic ć - joint and đ - joint at σ in Gσ when uv is not an edge.
