What is the angle of rotation of alphabet S
A "pure" trapezoid (a pair of parallel sides and two random sides) does not have rotational symmetry. If it is a parallelogram then it has a 180 degree symmetry. And if the paralloelogram happens to be a square, you have 90 deg symmetry.
The answer depends on which letter.
the line of symmetry from the middle
Sometimes called rotation symmetry, or symmetry of rotation. If you have an object that can be turned through a certain angle (like rotating a cube through 90o) and then it looks identical, then that object has a certain symmetry under rotation. If you can turn it through any angle, like a cylinder, then it has rotation (or rotational) symmetry.
None. You can rotate a circle by the smallest possible angle that you can think of and it will be an angle of symmetry. And then you can halve that angle of rotation and still have rotational symmetry. And you can halve that angle ...
If you can rotate (or turn) a figure around a center point by fewer than 360° and the figure appears unchanged, then the figure has rotation symmetry. The point around which you rotate is called the center of rotation, and the smallest angle you need to turn is called the angle of rotation. This figure has rotation symmetry of 72°, and the center of rotation is the center of the figure:
Yes. An isosceles triangle, for example, is symmetric about the bisector of its odd angle but has no rotational symmetry.
It is the axis of symmetry which is a line such that a object that is rotated at right angles to it becomes congruent to its original state before the angle of rotation reaches 360 degrees.
Yes, because if a regular polygon is turned around a specific point (the angle of rotation) and matches up again, it has rotation symmetry. For example, a hexagon is a regular polygon with six sides. All sides are the same length and the same size. When you turn it around the angle of rotation, it matches with the next side. Therefore, all regular polygons have rotational symmetry. Hope this helps!
A triangle can be rotated through any angle of your choice!An equilateral triangle has rotational symmetry of order 3, which means that a rotation of 120 degrees (or multiples) will bring it back to the same orientation. All other triangles have rotational symmetry of order 1: that is, you have to rotate them a full circle (360 deg) before they look the same.
Assuming the question is about ROTATIONAL symmetry rather than rational symmetry, the answer is none.
what is inclined at an angle of11.5 to earth's rotational axis?
They all have line symmetry except S
The star can be turned by 72°. Why 72°? The star has five points. To rotate it until it looks the same, you need to make 1 / 5 of a complete 360° turn. Since 1/5 * 360° = 72°, this is a 72° angle rotation. So yes, a five point star has rotational symmetry. :D
It is 360 degrees divided by the order of rotational symmetry.
Because if you rotate it about its center it looks different (not symmetric) no matter what the angle is.
The angle of rotation for a regular polygon with 7 sides isImmersive Reader
well, here are some. hexagons have 6 sides, six angles, rotational symmetry, three lines of symmetry, and the angle sum is 720. :) hope this helped.
A rhombus which has at least one angle a right angle (i.e. a square which is a special type of rhombus)
if it's not a square, 180 degrees
Earth's rotational axis has an inclination of 23.5 degrees. The angle is measured from a line that is perpendicular to Earth's plane of rotation (the Ecliptic).
The least angle at which the figure may be rotated to coincide with itself is the angle of symmetry.
