What does 'a line perpendicular to' mean?
It means that a line meets another line at right angles or 90 degrees
What is skewness measure between two perpendicular lines?
Two lines that are perpendicular to the same [third] line can meet at the same point, be parallel to one another or be skew. If you are not sure about that, see below for examples of all three cases.The skewness between the two perpendicular lines is the angle between the projection of one of the lines on the other.In vector analysis, if the direction vectors of the two perpendicular lines are a and b, then if x is the angle between them,cos(x) = a.b/(|ab|)where a.b is the scalar or dot product of aand b and,|a| and |b| are the magnitudes (lengths) of the two vectors.x is a measure of the skewness.Example:Imagine yourself in a cuboid room facing one of the walls. The line where the floor meets the opposite wall is the reference line.First consider the line where the left wall meets the floor and where the left wall meets the wall you're facing. Both these are perpendicular to the reference line. They meet: at the bottom-left-front corner of the room.Second, consider the line where the left wall meets the floor and where the right wall meets the floor. Both these are also perpendicular to the reference line. They never meet: they are parallel.Third, consider the line where the left wall meets the floor and the diagonal on the facing wall: from the top-left-front to the bottom-right-front. Again both these are perpendicular to the reference line. They are not parallel but they never meet either: they are skew.
How can you tell if a line is a function?
A line is a function ifany line parallel to the y axis meets the line at most once andall points where it does not meet the line are excluded from the domain.
What is point of intersection in math?
It is a point where one line (straight or curved) meets another line or a non-coplanar surface.
What does a perpendicular bisector do?
A perpendicular bisector [for a given line segment] is a line that meets it at 90 degrees and divides it into two halves.
