For other uses, see Perpendicular (disambiguation). In geometry, ii promissory notes or planes (or a line and a plane) be considered perpendicular (or orthogonal) to each other if they figure congruous bordering angles (a T-shape). The term whitethorn be used as a noun or adjective. Thus, as illustrated, the line AB is the perpendicular to CD through the point A. By definition, a line is endlessly long, and strictly spe aking AB and CD in this eccentric represent line segments of two infinitely long lines. so the line segment AB does not have to baffle line segment CD to be considered perpendicular lines, because if the line segments ar extended out to infinity, they would still form congruent adjacent angles. If a line is perpendicular to another as shown, all of the angles created by their convergency are called right angles (right angles measure ?/2 radians, or 90°). Conversely, any lines that meet to form right angles are perpendicular. In a coordinate plane, perpendicular lines have opposite correlative slopes. A horizontal line has slope equal to correct while the slope of a vertical line is describe as undefined or sometimes ±infinity. Two lines that are perpendicular would be denoted as AB[pic]CD Numerical criteria [edit] In terms of slopes In a Cartesian coordinate system, two corking lines L and M may be described by equations. L : y = ax + b M : y = cx + d as long as uncomplete is vertical.! Then a and c are the slopes of the two lines. The...If you ask to get a full essay, order it on our website: OrderEssay.net
