Which of the following describes the angle of rotation of a counterclockwise rotation?. . A.negative. B.positive. C.equal to 90 degrees. D.double the interior angle of the image. .
Using the common assumption for angles of rotation, it is common to assume that any rotation counterclockwise is a positive. Therefore, the answer is "B. Positive". Although it can also be "C. equal to 90 degrees", the rotation can also be less than or greater than 90 degrees. So B is the closest answer.
When no direction is specified, we understand that the rotation is counterclockwise. This means that any rotation in a positive number of degrees is counterclockwise.
