Abstract : The paper presents the descriptive geometry solution of the determination of the angles between geometric elements in a four-dimensional euclidean space. Incorporated in these solutions are the discussions of some problems of intersections between two geometric elements. These are: intersection of a line and a plane, belonging to the same 3-D space; intersection of two planes belonging to distinct 3-D spaces; intersection of a line and a 3-D space; intersection of a plane and a 3-D space.
