What does reflections mean in math?

A reflection is a transformation representing a flip of a figure. Figures may be reflected in a point, a line, or a plane. When reflecting a figure in a line or in a point, the image is congruent to the preimage. The fixed line is called the line of reflection.

What do you mean by 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. A satellite revolves around a planet.

What is a rotation of an image?

When referring to an image or image editor, rotate is a feature that allows you to turn an image in a clockwise or counterclockwise direction. For example, many editors allow you to rotate images 90, 180, or 270.

What is meant by rotation answer?

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 is revolve in science?

to move in a circular or curving course or orbit: The earth revolves around the sun. to turn around or rotate, as on an axis: The wheel revolves slowly.
