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.

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.
How do you rotate a figure around the point of origin?
To rotate a figure around the point of origin in a Cartesian coordinate system, you can use rotation formulas based on the angle of rotation (θ). For a counterclockwise rotation, the new coordinates (x', y') can be calculated using the formulas: x' = x * cos(θ) - y * sin(θ) and y' = x * sin(θ) + y * cos(θ). For a clockwise rotation, you can use the same formulas with a negative angle (-θ). Apply these calculations to each point of the figure to find its new position after the rotation.
What are the coordinates of the point (1 and ndash6) after a counter clockwise rotation of 90 and deg about the origin?
The coords are (6, 1).
How do you Rotate a figure 90 degrees clockwise to get 5 5 on a corridinate grid?
To rotate a figure 90 degrees clockwise around the origin on a coordinate grid, you can use the transformation rule: (x, y) becomes (y, -x). For the point (5, 5), applying this rule results in (5, -5). Therefore, after a 90-degree clockwise rotation, the new coordinates of the point are (5, -5).
What does angle of rotation mean in math?
In mathematics, the angle of rotation refers to the measure of the angle through which a figure or object is rotated around a fixed point, typically the origin in a coordinate system. It is usually expressed in degrees or radians and can be positive (indicating a counterclockwise rotation) or negative (indicating a clockwise rotation). This concept is essential in geometry, trigonometry, and various applications involving transformations and symmetry.
Rule for 180 degree clockwise rotation?
To rotate a figure 180 degrees clockwise, you can achieve this by first reflecting the figure over the y-axis and then reflecting it over the x-axis. This double reflection effectively rotates the figure 180 degrees clockwise around the origin.
What is the image of 1 -6 after a 180 degree counterclockwise rotation about the origin?
A 180° rotation is half a rotation and it doesn't matter if it is clockwise of counter clockwise. When rotating 180° about the origin, the x-coordinate and y-coordinates change sign Thus (1, -6) → (-1, 6) after rotating 180° around the origin.
What rule represents a 270 clockwise rotation about the origin?
270 rule represent a 270 rotation to the left which is very easy

How do you rotate a figure 270 degrees clockwise around the origin?
Move it 3 times* * * * *or once in the anti-clockwise direction.
What is the image of (1 -6) for a 180 counterclockwise rotation about the origin?
It is (-1, 6).Also, if the rotation is 180 degrees, then clockwise or anticlockwise are irrelevant.It is (-1, 6).
How do you you rotate a figure 90 degrees clockwise about the origin?
To rotate a figure 90 degrees clockwise about the origin, simply swap the x and y coordinates of each point and then negate the new y-coordinate. This is equivalent to reflecting the figure over the line y = x and then over the y-axis.
What are the coordinates of the point (1 and ndash6) after a counter clockwise rotation of 90 and deg about the origin?
The coords are (6, 1).

How do you rotate a figure 180 degrees clockwise about origin?
To rotate a figure 180 degrees clockwise about the origin you need to take all of the coordinates of the figure and change the sign of the x-coordinates to the opposite sign(positive to negative or negative to positive). You then do the same with the y-coordinates and plot the resulting coordinates to get your rotated figure.
What is the symbolic rule for a 45 degree rotation clockwise around the origin?
(x; y) --> (x.cos45 + y.sin45; x.sin45 - y.cos45)
