## What is the rule when rotating clockwise 90 degrees?

Here are the rotation rules: 90° clockwise rotation: (x,y) becomes (y,-x) 90° counterclockwise rotation: (x,y) becomes (-y,x) 180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y)

How do you rotate a figure 90 degrees clockwise about the origin?

A rotation by 90° about the origin is shown. The rule for a rotation by 90° about the origin is (x,y)→(−y,x) .

### Which direction is 90 degrees anticlockwise to the direction opposite?

The south-west makes 90° with south-east in clockwise direction. Whereas, north-east makes 90° with south-east in anti-clockwise direction. Hence, north-east is 90° anti-clockwise to the direction opposite to that of north-west.

What is the direction of anticlockwise?

Anticlockwise involves a turn to the left, against the direction of a clock’s hands. This is a positive rotation direction. Clockwise means moving in the direction of the hands of a clock. Anticlockwise is a direction opposite to that of the normal rotation of the hands of a clock.

## Is anticlockwise rotation positive or negative?

In physics, the counterclockwise direction is defined as positive and clockwise is negative for rotational variables. Figure 5. The rotation of a clock’s hands is the reference for defining rotational direction. Counterclockwise is the positive rotation direction and clockwise is the negative direction.

Is anticlockwise right or left?

Clockwise and anti-clockwise are ways of indicating the direction of a turn. So, what way is clockwise? Clockwise, involves a turn to the right as it follows the hands of a clock and anti-clockwise involves a turn to the left, against the direction of a clock’s hands.

### What is the difference between counterclockwise and anticlockwise?

When something moves in the opposite direction to the way in which the hands of a clock move round in known as counterclockwise. The counterclockwise direction is also known as the anticlockwise direction.

Is anticlockwise moment positive?

If a moment is moving ANTICLOCKWISE it is considered a POSITIVE moment. If a moment is moving CLOCKWISE it is considered a NEGATIVE moment.

## How do I get to anticlockwise?

So, what way is clockwise? Clockwise, involves a turn to the right as it follows the hands of a clock and anti-clockwise involves a turn to the left, against the direction of a clock’s hands.
