what is the locus of points equidistant from the points A(2,5) and B(4,5)?
Rate This Question!
Locus of points equidistant from two points, is perpendicular bisector of line determined by two points.

Given: A=(2,5) and B=(4,5)
Let (x, y) be a point on perpendicular bisector.

Distance b/w (x,y) and (2,5)= sqrt[(x-2)2+(y-5)2]
And b/w (x,y) and (4,5)= sqrt[(x-4)2+(y-5)2]

Equating and squaring both distances
By canceling and collecting terms

This is required equation. All points on it will be equidistant from A and B.
