Solution

- The triangle ABC and its image A'B'C' are just one quadrant from each other.

- This means that ABC was either rotated to the left in the shorter path 90 degrees or to the right at an angle of 270 degrees.

- However, a left rotation is in a counterclockwise direction while a right rotation is in a clockwise direction.

- Thus, we can conclude that this must be a 90-degree counterclockwise rotation.

- This is depicted below:
