What is Masturbation?​

Masturbation is the self-stimulation of the genitals to achieve sexual arousal and pleasure, usually to the point of orgasm (sexual climax).

Step-by-step explanation:

this is false ^.^ lol

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
