Point A has coordinates (x,y).
Point B (Point A rotated 270°) has coordinates (y,-x).
Point C (horizontal image of Point B) has coordinates (-y,-x).

A preimage and image are congruent in a rotation always sometimes or never?
Sometimes
What is the image of point 3 5 if the rotation is -270 degrees?
(-5,3)
What is the image of point (3 5) if the rotation is -90 degrees?
Conventionally positive angles are measured anticlockwise. It depends where the centre of rotation is, so where would you like the image to be? If the centre is at, say, (3, 5) then the image will be at (3, 5) regardless of the angle of rotation. If the centre is at, say, (3, 3) then the image will be at (5, 3) If the centre is at, say, the origin, ie (0, 0) then the image will be at (5, -3).
What is the image of point (4 3) if the rotation is -180 degrees?
Conventionally positive angles are measured anticlockwise, by 180° is a half turn regardless of direction. It depends where the centre of rotation is, so where would you like the image to be? If the centre is at, say, (4, 3) then the image will be at (4, 3) regardless of the angle of rotation. If the centre is at, say, (4, 4) then the image will be at (4, 5) If the centre is at, say, the origin, ie (0, 0) then the image will be at (-4, -3).
What is the image of (1 -6) for a 270 counterclockwise rotation about the origin?
It is (-6, -1).
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.
How to compose image with 360 degree rotation video?
If we rotate the video 360° in either direction, you should obtain the same image.
What is the image of point 4 3 if the rotation is 180?
(-4,-3) anything with a 180 degree rotation regardless of being postive or negative is always negative the numbers in parenthesis.
What is the image of point 3 and 5 if the rotation is 180 degrees?
What is the image of point (3, 5) if the rotation is
What is true about every rotation?
The image and pre-image are congruent.
What is the image of point (4 3) if the rotation is -180?
The answer will depend on where the centre of rotation is. Since that it not specified, the image could by anywhere.
What is true about every rotation in Geometry?
The image and pre-image are congruent.
What are the coordinates for an image on a dilation with a center at the origin?
it is nothing
What is the image of point (3 5) if the rotation is 90?
The answer depends on the centre of rotation. A rotation cannot be described without specifying the centre of rotation.
What is the image of point (3 5) if the rotation is -90?
The answer depends on the centre of rotation. A rotation cannot be described without specifying the centre of rotation.
What is the image of point 3 5 if the rotation is -90?
The answer depends on the centre of rotation. A rotation cannot be described without specifying the centre of rotation.
What is the image of point (-1-2) if the rotation is 90?
The answer depends on the centre of rotation. A rotation cannot be described without specifying the centre of rotation.
