Function Allocation. Function allocation (also known as task allocation) is a classic human factors method for deciding whether a particular function will be accomplished by a person, technology (hardware or software) or some mix of person and technology.
perpendicular - a straight line at right angles to another line straight line - a line traced by a point traveling in a constant direction; a line of zero curvature; the shortest distance between two points is a straight line 2. perpendicular - a Gothic style in 14th and 15th century England; characterized by vertical lines and a four-centered (Tudor) arch and fan vaulting
Two lines that intersect and form right angles are called perpendicular lines. The symbol â¥ is used to denote perpendicular lines. In Figure , line l â¥ line m. Figure 2 Perpendicular lines. Two lines, both in the same plane, that never intersect are called parallel lines. Parallel lines remain the same distance apart at all times. The symbol // is used to denote parallel lines. In Figure 3, l // m. Figure 3 Parallel lines.
