Answer 1

Blank one and two are both 4.

A square rotated about it send her by 360° maps onto itself at D) 4 different angles of rotation. You can reflect a square onto itself across B) 4 different lines of reflection.

A square is a geometric figure which has all its four sides equal and all its interior angles are right angles(90°.)
Therefore, it can be rotated about its center by 360°
It maps onto itself at 4 different angles of rotation (at every 90° angle).

We can reflect a square onto itself across 4 different lines of (2 across the non-parallel sides and 2 across the vertices of the square.) reflection.
