When documenting your network infrastructure, you are obtaining both hardware data to document your infrastructure's physical structure and software data to document the existence and configuration of the protocols in use on your network.
1. 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.
Defining Terms. Identify and name a pair of parallel lines, a pair of perpendicular lines, a ray, an angle, an arc, a circle, and a line segment. Use undefined terms to precisely define parallel lines, perpendicular lines, ray, angle, arc, circle, and line segment. Measuring Length and Angles. Apply the protractor postulate and angle addition postulate to calculate angle measures.
