# How do you describe rotation in math?

## How do you describe rotation in math?

Rotation turns a shape around a fixed point called the centre of rotation. Rotation is an example of a transformation. A transformation is a way of changing the size or position of a shape. The shape has been rotated 90° (a quarter turn) clockwise about the centre of rotation.

### What is a simple definition of rotation?

1a(1) : the action or process of rotating on or as if on an axis or center. (2) : the act or an instance of rotating something. b : one complete turn : the angular displacement required to return a rotating body or figure to its original orientation.

#### What is rotation example?

Rotation is the process or act of turning or circling around something. An example of rotation is the earth’s orbit around the sun. An example of rotation is a group of people holding hands in a circle and walking in the same direction. noun.

How do you explain rotation?

A rotation is a transformation that turns a figure about a fixed point called the center of rotation. An object and its rotation are the same shape and size, but the figures may be turned in different directions. Rotations may be clockwise or counterclockwise.

How do you write a rotation in geometry?

to form Image B. To write a rule for this rotation you would write: R270◦ (x,y)=(−y,x). Notation Rule A notation rule has the following form R180◦ A → O = R180◦ (x,y) → (−x,−y) and tells you that the image A has been rotated about the origin and both the x- and y-coordinates are multiplied by -1.

## What is rotation short answer?

“Rotation” refers to an object’s spinning motion about its own axis. For example, Earth rotates on its own axis, producing the 24-hour day. Earth revolves about the Sun, producing the 365-day year.

### What is rotation and revolution?

“Rotation” refers to an object’s spinning motion about its own axis. “Revolution” refers the object’s orbital motion around another object. For example, Earth rotates on its own axis, producing the 24-hour day. Earth revolves about the Sun, producing the 365-day year.

#### What is the rotation of the earth?

Earth’s Rotation Earth spins around its axis, just as a top spins around its spindle. This spinning movement is called Earth’s rotation. At the same time that the Earth spins on its axis, it also orbits, or revolves around the Sun. This movement is called revolution.

What is the equation for rotation?

Specific Rotation Formula and Calculation. The specific rotation of a substance is given by the following formula. [α] T λ = α / l.c. Where, α is the observer rotation of plane-polarized light, l is the path length of the light or the length of the sample cell, c is the concentration or the density of the sample.

What is the definition of rotation in geometry?

Rotation in mathematics is a concept originating in geometry. Any rotation is a motion of a certain space that preserves at least one point. It can describe, for example, the motion of a rigid body around a fixed point. A rotation is different from other types of motions: translations, which have no fixed points,…

## What is rotation of 270 degrees counterclockwise?

Rotating a Triangle 270 Degrees Counterclockwise: One such rotation is to rotate a triangle 270° counterclockwise, and we have a special rule that we can use to do this that is based on the fact that a 270° counterclockwise rotation is the same thing as a 90° clockwise rotation.

### What is geometric rotation?

Rotation is a geometric transformation R O, α defined by a point O called the center of rotation, or a rotocenter, and an angle α, known as the angle of rotation.
