<u><em>Explanation:</em></u> Congruence transformation is a transformation that does not change neither the side lengths nor the measures of the angles. This means that the formed image is an exact copy of the original figure
<u>Now, let's check the options:</u> <u>1- Shrinking:</u> This means that we are decreasing the side lengths. This option is incorrect
<u>2- Rotating:</u> This means that we are just changing the orientation of the figure without altering any measurements. This option is correct
<u>3- Reflecting:</u> This means that we are just changing the orientation of the figure without altering any measurements. This option is correct
<u>4- Stretching:</u> This means that we are increasing the side lengths. This option is incorrect
<u>5- Translating:</u> This means that we are just changing the position of the figure without altering any measurements. This option is correct
