A rotation is a transformation in a plane that turns every point of a figure through a specified angle and direction about a fixed point. The amount of rotation is called the angle of rotation and it is measured in degrees. You can use a protractor to measure the specified angle counterclockwise.

What is a rotation in math simple definition?
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 clockwise rotation is a negative magnitude so a counterclockwise turn has a positive magnitude.
What is the angle of rotation example?
For example, the carts on a Ferris wheel move along a circle around the center point of that circle. If a cart moves around the wheel once, the angle of rotation is 360°. If the cart was stuck halfway, at the top of the wheel, at that point its angle of rotation was only 180°.
What’s an angle in math?
In Euclidean geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles formed by two rays lie in the plane that contains the rays. Angles are also formed by the intersection of two planes.
What is rotation explain?
A rotation is a circular movement of an object around a centre of rotation. If three-dimensional objects like earth, moon and other planets always rotate around an imaginary line, it is called a rotation axis. If the axis passes through the body’s centre of mass, the body is said to rotate upon itself or spin.
What does clockwise mean in math?
Moving in the direction of the hands on a clock. (The opposite direction is called Counterclockwise or Anticlockwise.) Most screws and bolts are tightened, and faucets/taps are closed, by turning clockwise. See: Counterclockwise.
What is a clockwise angle?
If the rotation is counterclockwise, the angle has a positive measure. If the rotation is clockwise, the angle has a negative measure. An angle in standard position is said to lie in the quadrant where the terminal side resides. Coterminal Angles. One way to measure an angle is in degrees.
What is the angle of a clockwise rotation?
360° An angle generated by one complete clockwise rotation measures -360° or -21 radians.
What is a 90 clockwise rotation?
Answer: To rotate the figure 90 degrees clockwise about a point, every point(x,y) will rotate to (y, -x). Let’s understand the rotation of 90 degrees clockwise about a point visually. Then we can join the points and find the new positioned figure.
What is an angle answer?
In geometry, an angle can be defined as the figure formed by two rays meeting at a common end point. An angle is represented by the symbol ∠. Here, the angle below is ∠AOB. Angles are measured in degrees, using a protractor.
What are angles called?
Acute Angle – An angle less than 90 degrees. Right Angle – An angle that is exactly 90 degrees. Obtuse Angle – An angle more than 90 degrees and less than 180 degrees. Straight Angle – An angle that is exactly 180 degrees. Reflex Angle – An angle greater than 180 degrees and less than 360 degrees.
What is an angle for kids?
An angle is formed when two lines meet at a shared point. They are measured in degrees, which are represented by the symbol °. If you see an angle of 720°, it means it has rotated twice around a full circle. Angles in a circle add up to 360°.
