In math how do rotations affect coordinates?
A rotation turns a shape through an angle at a fixed point thus changing its coordinates
What is meant by slope in coordinate geometry?
Rise over run, generally change in y-coordinates divided by change in x-coordinates.
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).
What is the ratio of the change in the y-coordinates to the corresponding change in the x-coordinates as you move one point to another along a line called?
Slope. I'm pretty sure.
How are the size and the orientation of the triangle affected by the rotation?
The size does not change and the orientation is altered by the extent of the rotation.
Rule for 180 degree clockwise rotation?
change the sign, but DONT switch the coordinates (:
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.
In math how do rotations affect coordinates?
A rotation turns a shape through an angle at a fixed point thus changing its coordinates
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.
Does a hurricane ever change its direction of rotation?
No. A hurricane will not change its direction of rotation.
What are two important things gears do?
Change speed of rotation. change direction of rotation.
How do you calculate the coordinates of center of a rotation?
In the algebraic equation for a circle. (x - g)^2 + (y - h)^2 = r^2 'g' & 'h' are the centre of rotation.
Describe how to find the coordinates of the image of a point after a 270 degree rotation?
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).
What is meant by slope in coordinate geometry?
Rise over run, generally change in y-coordinates divided by change in x-coordinates.
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).
When reflecting a figure in the x-axis will you change all of the figures X coordinates or the y coordinates?
The y-coordinates.The y-coordinates.The y-coordinates.The y-coordinates.
What are Ireland's coordinates?
Ireland's geographic coordinates are 53 00 N, 8 00 W. Coordinates change over the years as the earth moves.
