The main idea is to show that constant angle surfaces in H²×R can be obtained by split quaternion product and the matrix representations. Also we give some related examples with their projections of figures.enConstant angle surfacesProduct manifoldSplit quaternionsA new representation of constant angle surfaces in H²×R with split quaternionsArticle6816336422618-6470
