In geometry, initially we learn about the fundamental concepts of point, line, line segments, ray, angles, types of angles, plane figures etc. When we learn about lines, we also learn about the Euclidean axioms on lines, points and lines. One of the axiom is only one line can be drawn through two distinct points in a plane. also we are familiar with the property that two non-parallel lines will intersect at one and only one point. In this section let us learn about the concurrent lines and the problems based on it.
|Parallel Lines and Perpendicular Lines||Perpendicular Lines and Intersecting Lines||A Horizontal Line||A Line of Sight|
|A Line of Symmetry||A Line Segment||A Ray Line||A Straight Line|
|A Tangent Line||A Vertical Line||Coplanar Line||Graphing Lines|
