It is 36k degrees where k is an integer.
It would require 36 degrees.
At every 9 degree turn it will look the same then after 40 turns it will map back on itself.
The smallest possible value above 0 degrees.
Rotation
A rotation of 360 degrees will map a parallelogram back onto itself.
A regular hexagon can be carried onto itself by rotations of 60 degrees, 120 degrees, 180 degrees, 240 degrees, and 300 degrees around its center. These rotations correspond to the multiples of 60 degrees, which are the angles formed by the vertices of the hexagon. Additionally, a 0-degree rotation (no rotation) also carries the hexagon onto itself.
It would require 36 degrees.
The regular octagon is the polygon that has a minimum rotation of 45 degrees to carry the polygon onto itself. An octagon has 8 sides, and when rotated by 360 degrees, it can be divided into 8 equal parts, resulting in a 45-degree rotation for each part. Thus, a rotation of 45 degrees maps the octagon onto itself.
A regular decagon can rotate onto itself at angles that are multiples of ( \frac{360^\circ}{10} ), which is ( 36^\circ ). This means it can rotate by ( 0^\circ ), ( 36^\circ ), ( 72^\circ ), ( 108^\circ ), ( 144^\circ ), ( 180^\circ ), ( 216^\circ ), ( 252^\circ ), ( 288^\circ ), and ( 324^\circ ). In total, there are 10 distinct angles (including ( 0^\circ )) at which the decagon can map onto itself.
The smallest number of degrees needed to rotate a regular pentagon around its center onto itself is 72 degrees. This is because a regular pentagon has five sides, and a full rotation is 360 degrees. Dividing 360 by 5 gives you the angle of rotation that maps the pentagon onto itself, which is 72 degrees.
A decagon has 10 sides, and its order of rotational symmetry is equal to the number of times it can be rotated to map onto itself. A regular decagon has rotational symmetry of order 10, meaning it can be rotated 36 degrees, 72 degrees, 108 degrees, and so on, up to 360 degrees, to coincide with its original position. Each rotation creates a position that is indistinguishable from the original, resulting in 10 unique rotational positions.
At every 9 degree turn it will look the same then after 40 turns it will map back on itself.
360/6 = 60 degrees.
The regular pentagon is the polygon that will carry itself onto itself when rotated by 72 degrees. This is because a pentagon has five equal sides and angles, and a rotation of 72 degrees corresponds to one-fifth of a complete turn (360 degrees). Each rotation by this angle aligns one vertex with the position of the next vertex, maintaining the polygon's symmetry.
Order 5. The shape will fit over itself exactly 5 times during a complete rotation.
An equilateral triangle can be rotated by 120 degrees or 240 degrees before it carries onto itself. This is because it has three equal angles of 60 degrees, and rotating it by any of these angles results in the triangle appearing unchanged. Hence, the minimum rotation needed to map it onto itself is 120 degrees.
The smallest possible value above 0 degrees.
