Click the buttons until you understand how the sketch works. When you are finished, reset the sketch with the circular arrows at top right. The first Reflection Line is x = 0. What is another name for this line? Write the coordinates of the Image points. Preimage A(1,2) reflects to A'( Preimage B(1,4) reflects to B'( Preimage C(2,5) reflects to C'( Preimage D(3,4) reflects to D'( Preimage E(2,3) reflects to E'( Preimage F(2.2) reflects to F'( If the Preimage had Point P(x,y) reflected over the y-axis, what are the coordinates of P'? Cycle through the Quadrants to be sure that your rule works. Change the Reflection Line to y = 0. What is another name for this line? Write the coordinates of the Image points. Preimage A(1,2) reflects to A'( Preimage B(1,4) reflects to B'( Preimage C(2,5) reflects to C'( Preimage D(3,4) reflects to D'( Preimage E(2,3) reflects to E'( Preimage F(2.2) reflects to F'( If the Preimage had Point P(x,y) reflected over the x-axis, what are the coordinates of P'? Cycle through the Quadrants to be sure that your rule works. If there is time, change the Reflection Line to y = x. Write the coordinates of the Image points. Preimage A(1,2) reflects to A'( Preimage B(1,4) reflects to B'( Preimage C(2,5) reflects to C'( Preimage D(3,4) reflects to D'( Preimage E(2,3) reflects to E'( Preimage F(2.2) reflects to F'( If the Preimage had Point P(x,y) reflected over y = x, what are the coordinates of P'? Cycle through the Quadrants to be sure that your rule works. If there is time, change the Reflection Line to y = -x. Write the coordinates of the Image points.
