Select the correct answer from each drop-down menu. 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.

darkknight:

what is the q? what are the answer choices?

kristenburns321:

these are weird because it has a drop down thing, but A square rotated about 360 degree maps onto itself at 1, 2, 3, or 4 different angles of rotation? You can reflect a square into itself across 2, 4. 8 or 16 different lines of reflection?

darkknight:

you can rotate a square by 90 degrees to get it to map itself, making it 4 times because 90 times 4 = 360

darkknight:

about reflecting teh square on itself draw lines and see how many time you can reflect
