Reflection
Point B is the reflection of point A in the blue mirror line.
A has co-ordinates (2,4). What are the coordinates of B?
Move A so that B is at (6,3).
The coordinates of A are:
Choose...
(3,-6)
(-3,6)
(6,3)
(3,6)
(6,-3)
(-6,3)
Result:
Move A to (-5,2). Can you move the mirror line so that B is at (5,-2)?
