To rotate a point ((x, y)) 90 degrees clockwise around the origin, you can use the formula ((x', y') = (y, -x)). This means the new x-coordinate becomes the original y-coordinate, and the new y-coordinate becomes the negative of the original x-coordinate.

What do you if both the coordinates are negative when doing a rotation of 90 degrees?

The answer will depend on whether the rotation is clockwise or anti-clockwise.


90 degrees clockwise rotation?

It is 1/4 of a turn


Is a 270 clockwise rotation the same as a 90 degree counterclockwise rotation?

Yes, a 270-degree clockwise rotation is the same as a 90-degree counterclockwise rotation. When you rotate an object 270 degrees clockwise, you effectively move it 90 degrees in the opposite direction, which is counterclockwise. Both rotations will result in the same final orientation of the object.


What is the image of the point (43) if the rotation is 90 degrees?

The answer will depend on whether the rotation is clockwise or counterclockwise.


What is the image of point (-1-2) if the rotation is 90 degrees?

The answer will depend on whether the rotation is clockwise or counterclockwise.


What is a rotation of 270 Degrees clockwise?

A rotation of 270 degrees clockwise is equivalent to a rotation of 90 degrees counterclockwise. In a Cartesian coordinate system, this means that a point originally at (x, y) will move to (y, -x) after the rotation. Essentially, it shifts the point three-quarters of the way around the origin in the clockwise direction.


What transformation could make an arrow pointing east become an arrow poiting north?

Rotation of 270 degrees clockwise or 90 degrees counter clockwise


What is point -5-2 rotated 90 degrees clockwise?

A transformation, in the form of a rotation requires the centre of rotation to be defined. There is no centre of rotation given.


Rule for 90 degree clockwise rotation?

we swap the co-ordinates and give the new y co-ordinate the opposite sign.90 degrees clockwise(y, -x)


What is (-53) 90 degrees clockwise?

ENE plus 90 degrees (clockwise) is SSE.


If you are facing east and you turn clockwise 90 degrees which direction will you be facing?

If you are facing east and you turn clockwise 90 degrees, you would be facing south. This is because a full circle is 360 degrees, so turning 90 degrees from east would bring you to the next cardinal direction, which is south.


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

To rotate a point or figure 90 degrees clockwise about the origin, you can use the transformation formula: for a point (x, y), the new coordinates after rotation will be (y, -x). Apply this transformation to each vertex of the figure. After calculating the new coordinates for all points, plot them to visualize the rotated figure.
