In the paper we examine the finite case of Grassmannian geometries arising from vector spaces and quadrics. Such geometries are configurations, whose detailed parameters we present. New methods to reduce quadratic forms over finite fields to canonical form, and to count subspaces on a quadric relative to a reflexive form are given.
