Question

to perform a rotation, what two pieces of information are necessary?

• direction and distance
• center and angle of rotation
• size and shape
• line of reflection

Explanation:

Rotation is a transformation that turns a figure around a fixed point, and the key required details are the fixed point (center of rotation) and the degree of the turn (angle of rotation). Direction and distance relate to translation, size/shape are unchanged in rotation, and line of reflection is for reflection transformations.

Answer:

Center and angle of rotation
