Quick Answer: What Is A Rotation In Geometry?

A rotation is a type of transformation that takes each point in a figure and rotates it a certain number of degrees around a given point. The result of a rotation is a new figure, called the image.

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 an example of a rotation?

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. The spinning motion around the axis of a celestial body.

What is rotation short answer?

“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 does rotation mean in science?

Rotation describes the circular motion of an object around its center. There are different ways things can rotate. 6 – 12+ Astronomy, Geography.

How do you find the rotation of a number?


  1. The rotation number of f is a rational number p/q (in the lowest terms). Then f has a periodic orbit, every periodic orbit has period q, and the order of the points on each such orbit coincides with the order of the points for a rotation by p/q.
  2. The rotation number of f is an irrational number θ.

Which figure is a rotation of the object?

Answer: In mathematics, rotation refers to the transformation that turns a figure about a fixed point called the center of rotation. Moreover, an object and its rotation are the same shape and size; however, the figures may be turned in different directions. In addition, rotation can be counter-clockwise or clockwise.

How do you rotate clockwise in geometry?

Here are the rotation rules:

  1. 90° clockwise rotation: (x,y) becomes (y,-x)
  2. 90° counterclockwise rotation: (x,y) becomes (y,x)
  3. 180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y)
  4. 270° clockwise rotation: (x,y) becomes (-y,x)
  5. 270° counterclockwise rotation: (x,y) becomes (y,-x)
