In geometry, two lines or planes (or a line and a plane) are considered perpendicular (or orthogonal) to each other if they form congruent adjacent angles (a T-shape). The term may be used as a noun or adjective. Thus, as illustrated, the line AB is the perpendicular to CD through the point B.
By definition, a line is infinitely long, and strictly speaking AB and CD in this example represent line segments of two infinitely long lines. Hence the line segment AB does not have to intersect line segment CD to be considered perpendicular lines, because if the line segments are 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 intersection are called right angles (right angles measure π/2 radians, or 90°). Conversely, any lines that meet to form right angles are perpendicular.
In a coordinate plane, perpendicular lines have opposite reciprocal slopes, which means that the product of their slopes is -1. A horizontal line has slope equal to zero while the slope of a vertical line is described as undefined or sometimes ±infinity. Two lines that are perpendicular would be denoted as ABFailed to parse (Missing texvc executable; please see math/README to configure.): \perp CD.

Plot: Shahid Khan is exiled after impersonating the legendary Sultana Daku in order to rob British trains. Now outcast, Shahid becomes a worker at Ramadhir Singh's colliery, only to spur a revenge battle that passes on to generations. At the turn of the decade, Shahid's son, the philandering Sardar Khan vows to get his father's honor back, becoming the most feared man of Wasseypur.

Plot: Wasseypur is no more the town that was once consumed by the raging war between Sardar Khan and Ramadhir Singh. It has spawned a new generation of money squandering lobbyists, turning into foolhardy gangs overnight. With illegal profiteering through scrap trade auctions over the Internet, corrupt government officials, election rigging and hooliganism, the town got murkier. Everyone wants alliance with the most powerful man of Wasseypur, Faizal Khan. His sole ambition however, is to annihilate Ramadhir Singh, the man with the grand scheme. Gangs of Wasseypur-Part 2 is a fitting conclusion to this story of vengeance, which by now, not just the family but also this town has come to inherit.
