Question

a triangle is rotated about p in the diagram. complete the sentence to accurately describe the degree of rotation in both directions. recall that clockwise rotations are written with a negative degree

Explanation:

Step1: Observe the perpendicular lines

The two dashed - lines are perpendicular, and the angle between them is 90 degrees.

Step2: Determine the rotation directions

For the counter - clockwise rotation from $\triangle ABC$ to $\triangle A'B'C'$, the angle of rotation is positive. For the clockwise rotation, it is negative.

Answer:

The counter - clockwise rotation is 90 degrees and the clockwise rotation is - 90 degrees.
