The objects shown below have experienced the rotations given by the arrows coding. In the space provided indicate an equivalent arrow coding that would produce the some image.

Solution

For single arrow coding, rotating the object about the the same axis 3 times but in opposite direction will produce the same image. For example in problem 1, 3, & 4

Solution 1. Equivalent arrow coding

--------> Z

--------> Z

--------> Z

Solution 2. Equivalent arrow coding

<-------- Y

<-------- Y

<-------- Y

Solution 4. Equivalent arrow coding

--------> Y

--------> Y

--------> Y

For double arrow coding, rotating the object about the same axis 2 times but in opposite direction will produce the same image. For example in problem 3.

Solution 3. Equivalent arrow coding

--------> X

--------> X
