Asquare 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. first blank: 1,2,3,4 last blank: 2,4,8,16

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.

The answer to the question is d
