To describe a shape's rotational symmetries, you would write the angle. For example, let's use a square. If you rotate a square 90 degrees, it will look exactly the same, and 180 will be the same too, so a square's rotational symmetries are 90 and 180 degrees.

Describe all of the point symmetries that a sphere would have?
A sphere has one point of symmetry (at its very center) if one considers rotational symmetry in its three dimensions. If one is only considering reflectional symmetry, it would have an infinite number of lines of symmetry.
How many rotational symmetries does a regular octagon have?
There are no right angles in an octagon.An 8 sided octagon normally has no right angles.
What are the properties of a decagon?
a figure that has 10 sides* * * * *It is a plane figure, bounded by ten straightlines, which meet in pairs at ten vertices.
What is the rotational symmetry of an octagon?
Rotational symmetry means it will look the same after being rotated a certain amount. Let's assume that you mean a regular octagon where the sides are all equal in length and the angles are all the same (135 degrees). With such an octagon, if you rotate it one turn to the right (that's 45 degrees), it will look just the same. Rotate another 45° and it is still the same. You can do this 8 times so we say that a regular octagon has an order of rotational symmetry of 8.
Why Bravais lattices are 14 in number?
Bravais lattices are classified based on their lattice symmetries, leading to 14 possible combinations of translational and rotational symmetries. These 14 Bravais lattices represent all possible ways in which a lattice can be arranged in 3D space while maintaining translational periodicity. Each Bravais lattice has unique characteristics that define its geometric arrangement.
What does rotational grazing mean?
rotational grazing mean the cows would eat all the grass and have no mor e grass to eat to pruduce milk
How many line of symmetry does a rectangle have?
a rectangle has 2 lines of symmetry: one runs from the center of one of the shorter sides to the center of the other short side. The second runs from the center of one of the longer sides to the center of the other longer side. Diagonals are not lines of symmetry.Many textbooks use what is called the folding test to find lines of symmetry of plane shapes. This tests says that when the folded part sits perfectly on top so that all the edges are matching, then the fold line is a line of symmetry. If we use this definition, then a diagonal is not a line of symmetry of a rectangle. We would find 2 lines of symmetry using this definition.Many books define both reflective and rotational symmetries. In fact, in more advanced algebra we look at groups that deal with this. Here is some interesting info about how that would would work with a rectangle. First you would need to identify the corners of the rectangle by using numbers or letters such as ABCD.Using this we can see two rotational symmetries and two reflective or line symmetries of the rectangle. Now think of symmetries as a function mapping the points of the rectangle back on themselves. Using this idea we can define the product of these functions or transformations. This would be one symmetry followed by another. A composition of symmetries.A rectangle has two lines of symmetry, each of which is a perpendicular bisector to two opposite sides of the rectangle.A rectangle has two lines of symmetry
How would a future historian describe you?
a historian would describe your life by you telling him all about you and your family.
What regular polygons have rotational symmetry?
All of them have rotational symmetry because all the sides and angles have to be the same in order for the polygon to be a regular polygon
Do all regular polygons have rotational symmetry?
no
How many letters have rotational symmetry?
I, H, N, O, S, X & Z all have rotational symmetry.
What is rotational kinematics?
Rotational kinematics is the study of the motion of objects that spin or rotate around an axis. It involves concepts such as angular velocity, angular acceleration, and rotational analogs of linear motion equations like displacement, velocity, and acceleration. Rotational kinematics helps describe how objects move and rotate in a circular path.
