2. Example: The graph shows the reflection of quadrilateral ABCD across line m. The reflection is written Rm(ABCD) → (A'B'C'D'). y A' A B 2 C'| DD C Esteban said R,(ABC) – (A'B'C'), where the equation of line n is x = 4, is the rule for the reflection. What was his error? 6 4 C 2 Вх 0 2. 4 6
In the case of the line n, the equation of the line is y=4, not x=4.
The axis of reflection is a line that is horizontal and constant for every value of x, at y=4. Is different from line m, where the axis of reflection is vertical.
