Question

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

Explanation:

Step1: Analyze the orientation of the shapes

The green shape and the gray shape are mirror - images. A flip (reflection) changes the orientation to match the mirror - image property.

Step2: Check for other necessary moves

Since the shapes are of the same size and the flip aligns them in terms of orientation, a slide (translation) is also needed to move the green shape to the position of the gray shape. A turn (rotation) is not required as rotation would not achieve the mirror - image alignment.

Answer:

A. Flip, C. Slide
