What We Did Today:
Students completed Problem 3.1, where they had to find a rule for reflecting coordinate pairs (and thus the flag figure) for three types of lines reflection: the y-axis, the x-axis and the line y=x. Notes are available below.
Focus Question:
How can you describe how points “move” under a reflection with coordinate rules in the form
(x, y) → ( ? , ? ) when the reflection line is: (1) the x-axis? (2) the y-axis? (3) the line y = x?
