Hi Rahul,

The rare questions on reflections usually involve only the x - axis, y - axis, x = y line and x = -y line.

I doubt if reflections on any other line will be asked.

Reflection of (a,b) on x-axis will be (a,-b)
Reflection of (a,b) on y-axis will be (-a,b)
Reflection of (a,b) on x=y will be (b,a)
Reflection of (a,b) on x=-y will be (-b,-a)

I hope this helps. Thanks.

Do we need to study the reflection of lines concept? Are they actually part of the test syllabus?
Yes, I've seen some of these questions, but they are very rare.
I concur with 4GMAT_Mumbai - those reflections are all you need (although I've never seen a question involving a reflection across the line y = -x (a.k.a. x = -y)

Cheers,
Brent
