Which statement best summarizes the rotations that turn a square onto itself?

Question

a. A square will rotate onto itself after a 180-degree rotation
b. A square will rotate onto itself after a 90-degree, 180-degree, 270-degree, and 360-degree
c. A square will rotate onto itself after a 90-degree rotation
d. A square will rotate onto itself after a 90-degree or 180-degree rotation

Answer 1

The statement that best summarizes the rotations that turn a square onto itself is:

b. A square will rotate onto itself after a 90-degree, 180-degree, 270-degree, and 360-degree

This is because a square can be rotated by 90 degrees, 180 degrees, 270 degrees, and 360 degrees, and in each case, it will look the same as it did before the rotation.
