How do you construct a perpendicular?
Last Updated: 25th May, 2020
- Place your compass point on P and swing an arc of any sizethatcrosses the line twice.
- Place the compass point on one of the two locations wherethearc crossed the line and make a small arc below the line (ontheside where P is not located).

Similarly one may ask, how do you construct a perpendicular line?
First, put the equation of the line givenintoslope-intercept form by solving for y. You get y = 2x+5, sothe slope is –2. Perpendicular lineshaveopposite-reciprocal slopes, so the slope of the line wewantto find is 1/2. Plugging in the point given into the equation y=1/2x + b and solving for b, we get b = 6.
One may also ask, how do you know if lines are parallel or perpendicular? If the slopes are the same and they-interceptsare different, the lines are parallel. Ifthe slopesare different, the lines are not parallel.Unlikeparallel lines, perpendicular lines dointersect.Their intersection forms a right, or 90-degree,angle.
Also question is, what is perpendicular example?
Parallel lines are lines in a plane that are alwaysthesame distance apart. Parallel lines neverintersect.Perpendicular lines are lines that intersect at aright (90degrees) angle.
What is the symbol for perpendicular?
