Answer: A square rotated about its center by 360º maps onto itself at D) 4 different angles of rotation. You can reflect a square onto itself across B) 4 different lines of reflection.
Step-by-step explanation:
A square is a geometric figure which has all its four sides equal and all its interior angles are right angles( ) .
Therefore, it can be rotated about its center by .
It maps onto itself at 4 different angles of rotation ( at every ).
We can reflect a square onto itself across 4 different lines of reflection (2 across the non-parallel sides and 2 across the vertices of the square).
