intersecting lines
Two lines cross or intersect at a point.
Parallel lines.
Two lines that cross each other are called "intersecting lines." At the point where they cross, they form angles. If the lines are not parallel, they will intersect at one specific point in a plane.
a segment
parallel lines
Two lines cross or intersect at a point.
The location two lines cross or intersect is called a vertex.
Parallel lines.
Two lines that cross each other are called "intersecting lines." At the point where they cross, they form angles. If the lines are not parallel, they will intersect at one specific point in a plane.
a segment
Lines that cross each other at 90 degrees are perpendicular lines.
"perpendicular"

They are perpendicular lines
the point of intersecting
Perpendicular
Mutually perpendicular.
