Exploring reflection across y-axis

Exploring Reflection across y-axis
Drag Snoopy who is standing on AB in QI .[br][br]1) What do you notice to Snoopy in QII?[br][br][br]2) What is the length of segment AB and A'B' ? [br][br][br]3) Find the perpendicular distance from A to y-axis and A' to y-axis? Then explain what do you notice.[br][br][br]4) Is this the reflection across y-axis or x-axis?[br][br][br]5) Can you predict a general rule in change of the coordinates in the pre-image (what will be the new coordinates of the image)[br][br]
