A square rotated about its center by 360º maps onto itself at _____ different angles of rotation. You can reflect a square onto itself across _____ different lines of reflection.
Answer for the first blank: 4 Answer for the second blank: 4

A square has 4 angles of rotation. This means you can rotate a square 4 times to have it line up with its original image before you hit 360 degrees.
A square has 4 lines of symmetry. They lines are the vertical and horizontal lines through the center. Also there are 2 diagonal lines of symmetry through the center. This makes 4 lines total.
