Abstract. The notion of angles is known in a vector space equipped with an inner product, but not well established in a vector space equipped only with a norm. In this note, we shall develop some notions of angles between two vectors in a normed space and discuss their properties.

Keywords: angles; inner product spaces; normed spaces; orthogonality
