Midpoint, Length And Perpendicular Bisector
Gbogbo ọrọ náà
Give the coordinates of two points and you can answer three natural questions at once: where is the point exactly between them, how far apart are they, and what line cuts the join in half at a right angle? These are the midpoint, the length, and the perpendicular bisector, three pillars of coordinate geometry.
In this lesson you will learn the midpoint and distance formulas and combine them with the perpendicular-gradient rule to construct a perpendicular bisector. The bisector pulls everything together: it passes through the midpoint and has the negative-reciprocal gradient of the segment it cuts.
