Study the diagram. The line l is perpendicular to line m (a) Is

Line Perpendicular to a line

The intersection of the planes 2x-y-3z=8 and x+2y-4z=14 is the line L .The value of for which the line L is perpendicular to the line through (a,2,2) and (6,1,-1) is

If the direction cosines of two lines are l_(1), m_(1), n_(1) and l_(2), m_(2), n_(2) , then find the direction cosine of a line perpendicular to these lines.

" If the line "l" - is perpendicular to the line which is passing through the points "(6,3),(-2,4)" then the slope of "l" is "

Two lines l and , are perpendicular to the same line n. Are l and m perpendicular to each other? Give reason for your answer.

Draw a line l. Take any point P on the line. Using a set square, draw a line perpendicular to the line l at the point p.

Draw a line AB. Take a point M anywhere outside the line. Using a compass and ruler, draw a line MN perpendicular to line AB.
