It will do so.

A figure has rotational symmetry when it can rotate onto itself in less than a full rotation.
It is a dodecahedron, and you can see images at the link below. Drawing it, though, depends on your artistic skill at projecting 3-d images onto 2-d.
Almost all flags are rectangular and so they cannot have rotational symmetry of an order greater than 2. The Union Jack is symmetrical after a 180 degree rotation and so has a symmetry of order 2.However, the flag is not symmetrical under reflection. This is because, although St Andrew's Cross (white) is symmetrically placed, St Patrick's Cross (red) is offset.
60 degrees. You find this by taking 360 and dividing by the total sides (6) which leaves you with the degrees of the exterior angles, this exterior angle is how little you can rotate any polygon for that matter.
add 2% to the total
A rotation of 360 degrees around the origin of (0, 0) will carry a rhombus back onto itself.
Rotation
A rotation of 360 degrees will map a parallelogram back onto itself.
120
Yes. A square needs only a quarter rotation.
It is 36k degrees where k is an integer.
At every 9 degree turn it will look the same then after 40 turns it will map back on itself.
A figure has rotational symmetry when it can rotate onto itself in less than a full rotation.
Any shape with a rotational symmetry of order 2 or more.
It would require 36 degrees.
That will depend on what type of triangle it is and if it is an equilateral triangle then it will have rotational symmetry to the order of 3
Yes. A rotation by any integer multiple of 45° will produce a figure that will superimpose on the original, un-rotated octagon. 45° 90° 135° 180° 225° 270° 315° as well as a full rotation of 360°.
