The quadratic embedding (QE) class of the connected graph G = (V, E) is determined based on its quadratic embedding constant (QEC) of the distance matrix graph G. The distance matrix is a conditionally definite negative, or equivalently if it admits a quadratic embedding in a Hilbert space, or if QEC of the graph G is non-positive. In this study, the classification for the hairy cycle graphs such as bearded cycle graph BC(k,m) for k is even, bearded cycle graph BC(3,m) and broken sun graph BS(4,m) will be calculated, and we derive the formulae of its QEC. These classes of graphs belongs to the QE class.
