Find the coordinates of the point of intersection of the perpendicular bisectors of the sides of a triangle
whose vertices are located at (-a, 0), (b, c), and (a, 0).
The perpendicular bisector of side is the y-axis, .Code:| | R | * (b,c) | * * *| * * | * P * | * Q - - * - - - - + - - - - * - - (-a,0) | (a,0) |
The slope of side is
. . The perpendicular slope is
. . . . The midpoint of side is
The equation of the perpendicular bisector of side is:
. . .
