Click on each of the boxes separately, then together to learn how the letter F behaves when reflected in two parallel lines. [br][br]Click on the grid button to see the coordinate grid. Record the coordinates of Point D for the preimage, then the image after each reflection. The Mirror2 line is a little off, so round the x-coordinate down.[br][br]Describe one transformation that would transform the preimage to the image after two reflections.[br][br]Move the lines by moving the point on Mirror1. Does your description still apply?[br][br]Answer the remaining questions on the worksheet.
