Question

how many times can a rectangle be reflected across an axis of symmetry so that it carries onto itself

Answer 1

Two times.

Or four times if the rectangle happens to be a square.

Answer 2

A rectangle can be reflected across an axis of symmetry so that it carries onto itself twice. Rectangles are geometric shapes with two lines of symmetry. One line of symmetry divides a rectangle in half horizontally, and the other line divides the shape in half vertically.
