Timur claims that all pre image and corresponding image points are "equidistant" from the line of reflection.
What do you think he means by "equidistant"? Do you agree?
3. How can you reflect each pre-image across the given line of reflection? How can you justify your image is a
reflection? See if your strategy works for reflecting the image across the line.
