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.
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.
360/6 = 60 degrees.
Order 5. The shape will fit over itself exactly 5 times during a complete rotation.
The smallest possible value above 0 degrees.
No. No shape with 7 or more sides will tessellate with multiple copies of itself. All traigles and quadrilaterals will tessellate, there are 14 irregular pentagons (the last was discovered in 2016), and a number of hexagons - including the regular hexagon.
Yes, but only in the form of some irregular concave decagons.
The rotation of the earth around the sun and the angle of the rotation of the earth itself.
If earth surrounds itself it is known as rotation if earth surrounds the sun then it is known as revolution
The earth rotates itself and rotates around the sun. a full rotation around the sun is exactly a year. a full rotation of the earth itself is a day.
Rotation
It will do so.
