## What is the rule for a degree 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)..

## Is a 180 degree rotation the same as a reflection?

The two motions (transformations) can’t be compared, since a rotation can be from and to any angle, but a reflection can only be horizontal or vertical. The reflection is the same as rotating the figure 180 degrees.

## What happens when you rotate a point 180 degrees clockwise?

How do you rotate a figure 180 degrees in anticlockwise or clockwise direction on a graph? 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).

## What are the rules for clockwise rotations?

Terms in this set (9)(-y, x) 90 degree rotation counterclockwise around the origin.(y, -x) 90 degree rotation clockwise about the origin.(-x, -y) 180 degree rotation clockwise and counterclockwise about the origin.(-y, x) 270 degree rotation clockwise about the origin.(y, -x) … (x, -y) … (-x, y) … (y, x)More items…

## Is 90 degrees clockwise the same as 270 degrees counterclockwise?

There is no difference between 90-degree Clockwise Rotation and 270-degree counter clockwise rotation.

## Why is a clockwise rotation negative?

A clockwise rotation is considered a negative rotation, so that, for instance, a rotation of 310° (counterclockwise) can also be called a rotation of –50° (since 310° + 50° = 360°, a full rotation (turn)).

## Is clockwise rotation positive or negative?

Counterclockwise is the positive rotation direction and clockwise is the negative direction. For example, a torque that rotates an object counterclockwise is a positive torque (see figure 6 below).

## What is the rule for a 180 degree rotation?

Rotation by 180° about the origin: A rotation by 180° about the origin is shown. The rule for a rotation by 180° about the origin is (x,y)→(−x,−y) .

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

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 negative 90 degrees 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 does a 180 degree rotation look like?

180 Degree Rotation When rotating a point 180 degrees counterclockwise about the origin our point A(x,y) becomes A'(-x,-y). So all we do is make both x and y negative.

## What is the rule for reflection?

The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same.

## 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.
