Abstract
A part of the structure of Hilbert spaces is characterized by the parallelogram law. In order for us to hold the parallelogram law by the norm, fairly good conditions are required for Banach space. In this paper, we propose new type parallelogram laws with a bifunction on Banach spaces, and consider alternative expression of affine combinations. Moreover, we introduce two different balanced mappings by using them.
