Answer :

To solve this problem, we assign coordinates to WXYZ and W'X'Y'Z'.

Let the coordinates be:

• W(0,0), X(1,1), Y(3,1) and Z(4,0)

,

• W'(0,0), X'(-1,-1), Y'(-1,-3) and Z'(0,-4)

Next, we check each of the rules and see the ones that give us the coordinates of W'X'Y'Z'.

Option A

• Reflection over x-axis: W*(0,0), X*(1,-1), Y*(3,-1) and Z*(4,0)

,

• Rotation 90 degrees clockwise: W'(0,0), X'(-1,-1), Y'(-1,-3) and Z'(0,-4)

This gives the required coordinate,

Answer here is Yes.

Option B

• Reflection over y-axis: W*(0,0), X*(-1,1), Y*(-3,1) and Z*(-4,0)

,

• Rotation 90 degrees clockwise: W'(0,0), X'(1,1), Y'(1,3) and Z'(0,4)

This does not gives the required coordinate,

Answer here is No.

Option C

• Reflection over y-axis: W*(0,0), X*(-1,1), Y*(-3,1) and Z*(-4,0)

,

• Rotation 90 degrees counterclockwise: W'(0,0), X'(-1,-1), Y'(-1,-3) and Z'(0,-4)

This gives the required coordinate,

Answer here is Yes.

Option D

• Rotation 90 degrees clockwise: W*(0,0), X*(1,-1), Y*(1,-3) and Z*(0,-4)

,

• Reflection over x-axis: W'(0,0), X'(1,1), Y'(1,3) and Z'(0,4)

This does not gives the required coordinate,

Answer here is No.

Option E

• Rotation 90 degrees clockwise: W*(0,0), X*(1,-1), Y*(1,-3) and Z*(0,-4)

,

• Reflection over y-axis: W'(0,0), X'(-1,-1), Y'(-1,-3) and Z'(0,-4)

This gives the required coordinate,

Answer here is Yes.

Option F

• Rotation 90 degrees counterclockwise: W*(0,0), X*(-1,1), Y*(-1,3) and Z*(0,4)

,

• Rotation 180 degrees: W'(0,0), X'(1,-1), Y'(1,-3) and Z'(0,4)

This does not give the required coordinate,

Answer here is No.
