Beam of light
Straight lines that never cross are called parallel lines.
Two straight lines that remain equal distance apart are parallel lines.
If two lines have the same gradient, then this means they are travelling in the same direction. Lines travelling in the same direction will never touch or cross each other even if extended to infinity. Lines with such a property are called "parallel lines." This is assuming they are not just exactly the same line.
When 2 or more straight lines meet...the point where they meet is called the point of intersection
rays.
A shape with 4 straight lines in which there are 2 parallel and 2 unparallel lines is called a Trapezium.
A polygon.
Perpendicular lines or parallel lines are two examples
an intersection
The phenomenon where light waves travel in straight lines is called rectilinear propagation. This means that light travels in a straight path unless it encounters a medium that causes it to change direction.
Intersecting Lines. Two lines next to each other but go straight and never meet are called parallel lines. Perpendicular is when two lines cross right into the middle and makes 4 right angles (90 degrees). you!! :)
yes their is it is called a paralel two straight lines never meet
