Negative Reciprocals and Perpendicular Lines

in MES Science5 months ago (edited)

In this video I discuss negative reciprocals and prove that the intersection of two lines that have slopes which are negative reciprocals of each other are indeed perpendicular, or intersect at right angles (or 90 degrees).

Proof that Negative Reciprocals are Perpendicular

Now we prove that the intersection of 2 lines that have their slopes "negative reciprocals" of each other are indeed perpendicular.


By observation, the intersection is perpendicular as it is just the same line rotated by 90 degrees clockwise.
