The reflection in the line y=x is A'(-1, 2), B'(2, -1), C'(3, 2) and D'(2, 4)
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
The reflection of a point A(x, y) in the line y = x is A'(y, x).
The polygon has vertices at A(2, -1), B(-1, 2), C(2, 3) and D(4, 2). The reflection in the line y=x is:
A'(-1, 2), B'(2, -1), C'(3, 2) and D'(2, 4)
