Can you rotate the letter D (less than 360 degrees) where it still looks like an upright "D"?
OpenStudy (lgbasallote):
rotational symmetry means if you rotate i , it always stays the same figure
OpenStudy (lgbasallote):
rotate it*

no i thought it was that you can rotate it less than 360 degrees and it will along the way look like its orignal shape
OpenStudy (anonymous):
like the capital letter I
jimthompson5910 (jim_thompson5910):
no lgbasallote, the figure below
|dw:1343346061193:dw|
**It should be a square***
has rotational symmetry
jimthompson5910 (jim_thompson5910):
since you can rotate it 90 degrees and it will match up with the original figure
