It is symmetric, so the rotation would be useless, it would still look the same.
turn one quarter of the way.
A square has 4 right angles. Right angles are 90 degree angles.4*90 degrees = 360 degrees
Square = 90 degrees Pentagon = 72 degrees
{1 0} {0 -1}
A right angle is 90 degrees. The square root of a right angle would be the square root of 90, which is 9.486.
No, a square cannot rotate onto itself at 90 degrees. When a square is rotated by 90 degrees, its orientation changes, and it does not match its original position. However, it can be rotated by 90 degrees and still appear the same due to its symmetrical properties, but it is not the same configuration as its starting point.
I dOnt now
rotate it 90 degrees
It rotates 90 degrees.
Yes
yes
To describe a shape's rotational symmetries, you would write the angle. For example, let's use a square. If you rotate a square 90 degrees, it will look exactly the same, and 180 will be the same too, so a square's rotational symmetries are 90 and 180 degrees.
90 degrees
The text will rotate 90 degrees to the right. The beginning of the text will be at the top. If you rotate another 90 degrees, the text will display upside down.
Yes
you open it with a picture editor, rotate it 90 degrees and save it.
It goes right round 360 degrees in 24 hours, so 6 hours for 90 degrees, relative to the Sun. Relative to the distant stars, it takes the Earth about 5 hours, 59 minutes to rotate 90 degrees.
