Which of the following are congruence transformations? A. Shrinking B. Rotating C. Reflecting D. Stretching E. Translating

Rotating
Reflecting
Translating

Explanation:
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

Now, let’s check the options:
1- Shrinking: This means that we are decreasing the side lengths.
This option is incorrect

2- Rotating: This means that we are just changing the orientation of the figure without altering any measurements.
This option is correct

3- Reflecting: This means that we are just changing the orientation of the figure without altering any measurements.
This option is correct

4- Stretching: This means that we are increasing the side lengths.
This option is incorrect

5- Translating: This means that we are just changing the position of the figure without altering any measurements.
This option is correct
