## What are the rules for clockwise rotations

180 degrees is (-a, -b) and 360 is (a, b).

360 degrees doesn’t change since it is a full rotation or a full circle.

Also this is for a counterclockwise rotation.

If you want to do a clockwise rotation follow these formulas: 90 = (b, -a); 180 = (-a, -b); 270 = (-b, a); 360 = (a, b)..

## What are the rules for rotation

Rules of Rotation There are some general rules for the rotation of objects using the most common degree measures (90 degrees, 180 degrees, and 270 degrees). The general rule for rotation of an object 90 degrees is (x, y) ——–> (-y, x).

## What does 90 degrees look like

In geometry and trigonometry, a right angle is an angle of exactly 90° (degrees), corresponding to a quarter turn. … The term is a calque of Latin angulus rectus; here rectus means “upright”, referring to the vertical perpendicular to a horizontal base line.

## How many reflection lines are there in a rotation

two reflectionsA rotation equals two reflections.

## 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.

## What is the meaning of rotation

noun. the act of rotating; a turning around as on an axis. Astronomy. the movement or path of the earth or a heavenly body turning on its axis. one complete turn of such a body.

## Can a reflection be a rotation

The composition of reflections over two intersecting lines is equivalent to a rotation.

## What is the difference between a rotation and a reflection

Reflection is flipping an object across a line without changing its size or shape. Rotation is rotating an object about a fixed point without changing its size or shape. Translation is sliding a figure in any direction without changing its size, shape or orientation.

## What are the rules for 90 degrees clockwise and counterclockwise

When we rotate a figure of 90 degrees counterclockwise, each point of the given figure has to be changed from (x, y) to (-y, x) and graph the rotated figure.

## What is the rule for a 360 degree rotation

For example a rotation of -90° about the origin is a rotation 90° clockwise about the origin. 360° Rotation A rotation of 360° about a point returns a figure to its original position. That is, the image under a 360° rotation is equal to the preimage.

## What is a 180 degree rotation

Rotation of a point through 180°, about the origin when a point M (h, k) is rotated about the origin O through 180° in anticlockwise or clockwise direction, it takes the new position M’ (-h, -k). … Worked-out examples on 180 degree rotation about the origin: 1.

## How do you tell if a rotation is clockwise or counterclockwise

Rotations may be clockwise or counterclockwise. When working in the coordinate plane: assume the center of rotation to be the origin unless told otherwise. assume a positive angle of rotation turns the figure counterclockwise, and a negative angle turns the figure clockwise (unless told otherwise).

## What are the 4 types of transformation

There are four main types of transformations: translation, rotation, reflection and dilation. These transformations fall into two categories: rigid transformations that do not change the shape or size of the preimage and non-rigid transformations that change the size but not the shape of the preimage.

## How can you tell if a motion is a reflection

A reflection is when a shape flips. In this case, the triangle has flipped to the right over an imaginary line in the center. You can flip a shape in any direction and over any part of itself, but this can be a little harder to visualize on your own, so here is a picture showing some other types of flips.

## What is the rule for a 90 degree clockwise rotation

Rule : When we rotate a figure of 90 degrees clockwise, each point of the given figure has to be changed from (x, y) to (y, -x) and graph the rotated figure. Let us look at some examples to understand how 90 degree clockwise rotation can be done on a figure.

## Is R rotation or reflection

A rotation of θ degrees (notation RC,θ ) is a transformation which “turns” a figure about a fixed point, C, called the center of rotation.
