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 turn can change the orientation. Since there is no mirror - like reflection (flip is not needed as the shapes are not mirror - images in a way that flip would align them directly), a turn (rotation) is required to make the orientation match.

Step2: Analyze the position

After turning (if needed), a slide (translation) is required to move the green shape to the position of the gray shape.

Answer:

A. Slide, C. Turn
