Nettet14. jun. 2016 · This plugin merges segments of a line network (e.g. river network) in order to simplify its topology. Two merging methods are currently available : length (a segment is merged with its longest neighbor) and alignment (a segment is merged with its best aligned neighbor). UPDATE: NettetIntersecting lines are lines that meet each other at one point. It’s amazing how a simple definition can lead us to know important properties about linear equations’ angles and … The intercept theorem, also known as Thales's theorem, basic proportionality theorem or side splitter theorem is an important theorem in elementary geometry about the ratios of various line segments that are created if two intersecting lines are intercepted by a pair of parallels.

"NettetIn geometry, an intersection is a point, line, or curve common to two or more objects (such as lines, curves, planes, and surfaces). The simplest case in Euclidean geometry is the line–line intersection between two distinct lines, which either is one point or does not exist (if the lines are parallel ).
