Congruence and Transformations

Question 8 • SRC 2022 M/J Grade 8 Pre-Algebra Q1

Do you think a sequence of translations across the x- or y-axis and/or reflections on a figure could result in the same image as a 90-degree clockwise rotation? Explain why or why not.

Answer

Answer:

No, it is not possible. A 90-degree clockwise rotation changes the position of the x- and y-coordinates (transforming (x, y) into (y, -x)). Translations and reflections across the x- or y-axis only change the signs or values of the coordinates, but they cannot swap the order of the x and y values itself. Therefore, you cannot achieve the same result as a rotation using only these transformations.
