Question

a regular octagon is centered at the origin. give 2 transformations that will map the pre image onto itself

Answer 1

A regular octagon centered at the origin can have a few transformations that will yield the same image. Octagons have rotational symmetry of 45 degrees so rotating increments of 45 degrees will move the octagon's image to the pre-image. examples could be rotating 45 degrees and rotating 90 degrees
