It's certainly possible. Draw a square and rotate it by 45 degrees - it looks like a diamond.
Its Orientation
yes
The same as 180 degrees clockwise. What do you mean "the answer to"?
A circle is the set of all the points that have the same distance from a given point (its center). If you rotate a shape, you rotate it in such a way that you keep any point a fixed distance from the center of rotation.
180 degrees
rotate it 90 degrees
if you have a shape in quadrant 1 of a coordinate plane and another shape in quadrant 2, rotate the shape in quadrant 1 to the right 90 degrees. It, when rotated, the shape in quadrant 1 is congruent to the shape in quadrant 2, then they are rotationally symmetrical.
It rotates 90 degrees.
It only has rotional symmetry if it can be rotated around a point less than 360 degrees and staying the same shape like if you rotate a square 90 degrees it will be the same shape as in the beginning.. Kind of confusing
No a pigeon can not rotate its head 360 Degrees
15 degrees
It's certainly possible. Draw a square and rotate it by 45 degrees - it looks like a diamond.
A horse can rotate its ears as far as 180 degrees.
Its Orientation
Yes
122.5 degrees
