Abstract
Addition formulae of trigonometric and elliptic functions are used to generate Bäcklund transformations together with their connecting quadrilateral equations. As a result, we obtain the periodic solutions for a number of multidimensionally consistent affine linear and multiquadratic quadrilateral equations.
