Parallel line segments are any two line segments that run parallel to each other, which means that they will never cross. The length or thickness of each line does not matter.
Continue ReadingIn theory, all line segments are infinitely long. For practical purposes, people work with line segments, which are sections of the line. When there are two line segments, they can either be parallel to each other, perpendicular or neither. Parallel lines are always the same distance from each other. Perpendicular lines intersect each other at 90-degree angles. Finally, it is possible for lines or line segments to cross each other at an angle other than 90 degrees.

An angle bisector is a line that divides an angle into two equal angles; it is often depicted as a ray emanating from an angle's vertex.
Full Answer >The point of tangency is the point at which a line touches an ellipse or circle, assuming that the line only makes contact at one point. The line running through the point of tangency only has that one point in common with the circle or ellipse, and it is called a "tangential" line with respect to that shape.
Full Answer >The slope of any horizontal line is always zero. The word "slope" is defined as the incline or the steepness of a straight line. If a line is horizontal, there is no incline.
Full Answer >The side splitter theorem states that if a line parallel to one side of a triangle intersects with the other two sides, it divides those two sides proportionally. This theorem can be used to solve many similar triangle math problems.
