Pick the coordinates of the image of A under the point symmetry centred at S.
A = (-3, 2) · S = (1, 1)
Pick A′ = the image of A under the symmetry about S:
What does this generator do?
The generator places a point A and a centre of symmetry S on a coordinate grid. Pick A′ from four options.
How to solve it
Formula: A′ = 2·S − A. The centre S is exactly the midpoint of segment AA′, so it "mirrors" A to the same distance on the opposite side.
