Which shows the pre-image of triangle x’y’z’ before the figure was rotated 90° about the origin?

Answer:- The preimage before the figure was interchanged 90° around the origin is at X (2, 2), Y (6, 0) and Z (1, -1)

What is transformation?

Transformation refers to the movement of a point from the initial location to a new site. Kinds of transformation are reflection, rotation, translation and dilation.

If a point A (x, y) is interchanged 90° around the origin, the new point is at A'(-y, x)

Triangle X’Y’Z’ is at X'(-2, 2), Y'(0, 6) and Z'(1, 1). Henceforth the preimage before the figure was rotated 90° around the origin is at X (2, 2), Y(6, 0) and Z(1, -1)
