For other uses, see Perpendicular (disambiguation). In geometry, dickens melodic phrases 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 speaking AB and CD in this e ccentric 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 atomic number 18 extended let on 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 production 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 interchangeable slopes. A horizontal line has slope equal to nada while the slope of a vertical line is set f orth as undefined or sometimes ±infinity. T! wo lines that are perpendicular would be denoted as AB[pic]CD Numerical criteria [edit] In terms of slopes In a Cartesian coordinate system, two straight 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 deprivation to get a full essay, order it on our website: OrderEssay.net
