trigonometry


Triangle Geometry Query


I'm hoping someone can help me out. My trigonometry is a bit rusty!
See link below. I know all three coordinates and all three distances. What I want to calculate are the coordinates of the red dot!
I'm hoping it might be an easy answer for a mathematician out there?
Click here to see illustration of the triangle and required coordinate
If triangle is isosceles:
Find bisector vector, normalize it, take vector with length d3 from (X3,Y3) point
DX = X1 + X2 - 2 * X3
DY = Y1 + Y2 - 2 * Y3
Len = Sqrt(DX * DX + DY * DY)
RedX = X3 + d3 * DX / Len
RedY = Y3 + d3 * DY / Len
