The point `Q` is the image of the `P` in line `x + y+ 4= 0` and `R` is the image of `Q` in line `2x-y + 7=0.` If `P = (1,6),` then the circumcentre of triangle `PQR` is

The point B is image of a in the line x+y+4=0 and C is the image of B in the line 2x-y+2=0. If A =(1,2) then circum diameter of triangle ABC is

The point Q is the image of the point P(1,5) about the line y=x and R is the image of the point Q about the line y= -x . The circumcentre of the DeltaPQR is

The point Q is the image of the point P(1,5) about the line y=x and R is the image of the point Q about the line y=-x. The circumcentre is the DeltaPQR is

Find the image of the point P(1, 2) in the line x-3y+4=0

The point of injtersection of the line x/p+y/q=1 and x/q+y/p=1 lies on the line

The point of injtersection of the line x/p+y/q=1 and x/q+y/p=1 lies on the line

The point P (2,-4) is reflected about the line x = 0 to get the image Q. Find the co-ordinates of Q.

The point P(3,6) is first reflected on the line y=X and then the image point Q is again reflected on the line y=-X to get the image point Q'. Then the circumcentre of the Delta PQQ' is
