Definition pentagontriangle {C : category} (tuua : tensor_unit_unitors_associator C) : UU := triangle_identity (tensor_unit_unitors_associator_laxleftunitor tuua) (tensor_unit_unitors_associator_laxrightunitor tuua) (tensor_unit_unitors_associator_laxassociator tuua) × pentagon_identity (tensor_unit_unitors_associator_laxassociator tuua).
