Sagot :
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.
