The rule of reflection is ry-axis (x , y) → (-x , y) ⇒ 2nd answer
Step-by-step explanation:
Let us revise some transformation
- If point (x , y) reflected across the x-axis
, then its image is (x , -y)
, the rule of reflection is rx-axis (x , y) → (x , -y)
- If point (x , y) reflected across the y-axis
, then its image is (-x , y)
, the rule of reflection is ry-axis (x , y) → (-x , y)
∵ The first quadrilateral has vertices
A (-2 , 1) , B (-4 , 1) , C (-4 , 5) , D (-2 , 4)
∵ The second quadrilateral has vertices
A' (2 , 1) , B' (4 , 1) , C' (4 , 5) , D' (2 , 4)
- The x-coordinates of point A' , B' , C' , D' have the same values
and opposite signs of the x-coordinates of points A , B , C , D
∴ A' , B' , C' , D' are the images of A , B , C , D after reflection
across the y-axis
∴ The rule of reflection is ry-axis (x , y) → (-x , y)
The rule of reflection is ry-axis (x , y) → (-x , y)
