How often are two non-coplanar lines that are perpendicular to the same line are parallel to each other?
Never. If they are parallel then the original line and the two perpendiculars would be coplanar which, they are required not to be.
What is projection of line?
The line joining the feet of the perpendiculars drawn from all the points of the line onto a preselected plane.
How many perpendiculars can we draw to a line from a given point outside the line?
In a Euclidean plane, only one.
What is the name of the line drawn perpendiculars to the surface where the light rays strikes?
A normal line is the name of the line drawn perpendicular to the surface where a light ray strikes.
How do you draw a line parallel to a given line?
[A Parallel line is a straight line, opposite to another, that do not intersect or meet.] Ie. Line 1 is Parallel to Line 2. ------------------------------------------------- <Line 1 ------------------------------------------------- <Line 2
What is a line which cuts parallel line?
The line that cuts a parallel line is called a TRANSVERSAL. When you have parallel lines and you want to show like corresponding, vertical, ect.... then the line that cut through the parallel lines is a TRANSVERSAL
How do you find a slope of a line parallel?
Line a is parallel to line b, m, and . Find .
What is the need of parallel line algorithm?
Do you mean "Why might a parallel line algorithm be needed?" or "What properties does a parallel line algorithm need to have?".
What is the slope of a line parallel to a vertical line?
A vertical line has an undefined slope. For the line to be parallel to a vertical line, the slopes would have to be the same. Therefore, the line parallel to a vertical line also has an undefined slope.
How do you draw a parallel line with a set square?
draw line st parallel to line mn
How do you classify a parallel line?
I classify a parallel line as two line segments that will never intersect if the line kept going. They are perfectly straight and even.
What is the difference between parallel and perpendicular line on rectangle?
The difference between a perpendicular line and a parallel line is that a perpendicular line crosses or joins, while a parallel line doesn't touch at all.
