Question

how would you move the green shape exactly over the gray shape using the fewest moves? check only necessary moves.
a. slide
b. flip
c. turn

Explanation:

Step1: Analyze the orientation of the shapes

The green shape and the gray shape have different orientations. A flip or a slide won't change the orientation in the way needed. A turn (rotation) is required to match the orientation.

Step2: Consider the movement

Since the main difference is in orientation (not just position which a slide would address, and not a mirror - image which a flip would address), the key move is a turn.

Answer:

C. Turn
