A geo- triangle
Set squares are useful for drawing parallel lines and perpendicular lines.
In drawing it is the point at which parallel lines appear to converge.
crossing a cheque is a process of drawing two parallel lines on a cheque with or without certain words
Isometric drawings are drawn to the same scale along all three axes (x,y,z) so are useful for giving a sense of relative dimensions, and three dimensional scale. Measurements can also be taken from the drawings for items that lie along or parallel to an axis.
Well a parallelogram is a 4 sided shape with 2 pairs of parallel lines, hence PARALLELogram. That's the reason, because there are two pairs of parallel lines.
When two lines are parallel, then they do not intersect.
It device used by an engineer for drawing parallel lines,lanes in some angle etc.It is used in engineering graphics.
If they were not actually parallel then they would not be parallel lines!
Construction, engineering, drawing, and architecture all use parallel and perpendicular lines. Other than that, it is an important topic because you are learning how to apply the language and tools of mathematics to an intuitive system. These topics have proven important in the history of human kind and also many before you have shown that by learning about parallel and perpendicular lines, one learns how to use math and logic. It is doubtful that you can make a living off of parallel and perpendicular lines, but if you can't understand parallel and perpendicular lines, then I worry about your future.
no parallel lines
it has parallel lines
parallel lines are diagonal lines or increasing lines
