You have to switch the x and y coordinates and multiply your new x coordinate by -1. You can also dram the point and rotate your paper physically by 90 degrees.

Example:

Your Coordinates: (3,8)

New Coordinates: (-8,3)

(3,8) ---> (8,3) ---> (-8,3)

Another Ex: (-7,-1) --> (-1,-7) --> (1,-7)

It is (-1, 6).Also, if the rotation is 180 degrees, then clockwise or anticlockwise are irrelevant.It is (-1, 6).

The point with coordinates (p, q) will be rotated to the point with coordinates [(p - q)/sqrt(2), (p + q)/sqrt(2)].

The x,y origin is 0,0

Rotating it about the origin 180° (either way, it's half a turn) will transform a point with coordinates (x, y) to that with coordinates (-x, -y) Thus (2, 5) → (-2, -5)

270 rule represent a 270 rotation to the left which is very easy

You dont, its just 90 degrees 3 times..

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.

Move it 3 times* * * * *or once in the anti-clockwise direction.

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.

I dont really know if this is right but i think to do this problem you have to take a point then rotate the paper counter clockwise around the origin then you have a new point which is called a prime. Then reflect it over the y axis on the graph.

No, only their positions will change.

Visualize a capital "N." Rotated 90 degrees counter-clockwise (a quarter turn to the left) it would look like a capital "Z."

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.

The coords are (6, 1).

The coordinates of the given 90 degree (Counter-clockwise) about the origin from the given vertices J(-2,1), K(-1,4), L(3,4), M(3,1) will be: J(-2,1): (-2, -2) K(-1,4): (-4, -1) L(3,4): (4, 3) M(3,1): (1, 3)

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.

It is (-1, 6).Also, if the rotation is 180 degrees, then clockwise or anticlockwise are irrelevant.It is (-1, 6).
