What properties of a figure are preserved under a rotation?

Answer with explanation:

The main properties of rotation are as follows :-

1. The rotation preserves side-length and angles.

2. It creates congruent figures.

3. The rotations of 360° map a figure onto itself.

4. The lines connecting the center of rotation to the pre-image and the corresponding point on the image have equal length.

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
