Answer 1

Answer:

rotation of 90 degrees counterclockwise centered at the origin

Step-by-step explanation:

Just look at one single point of A and what must happen to it to become the corresponding point in B.

Look at point (2, 1) in figure A. Draw a segment from (0, 0) to (2, 1).

The corresponding point in figure B to (2, 1) is (-1, 2). Now draw a segment from (0, 0) to (-1, 2). Look at the relationship between the two segments.

The segment (0, 0) to (2, 1) is perpendicular to the segment (0, 0) to (-1, 2).

The transformation is a rotation of 90 degrees counterclockwise centered at the origin.
