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)

How do you rotate a figure 270 degrees clockwise about origin?

You dont, its just 90 degrees 3 times..


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

Take any one point on the figure. Draw a line from it to the origin. At the origin measure an angle of 90 degrees (right angle) in a clockwise direction. Draw a line from the origin at this new angle and of the same length as the original angle. Repeat this process for the other points in the figure. NB Be careful, there will be numerous lines from the origin. At the end points of the new lines, connect up to reveal the origin figure ,but rotated 90 degrees - clockwise.


How do you rotate a figure 270 degrees clockwise around the origin?

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


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.


How do you rotate a figure 90 degrees counter clockwise then reflect over y axis?

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.


Will the sides of the triangle change if rotate a figure 90 degrees clockwise about origin?

No, only their positions will change.


How do you rotate a figure 180 degrees about origin?

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


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).


The vertices of a polygon are given. Name the coordinates of the given number of degrees about the origin. J(-2,1) , K(-1,4) , L(3,4) , M(3,1) ; 90 degree (Counter-clockwise)?

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)


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 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).


What quadrant does -135 degrees?

Third quadrant. From the origin (0,0) and on the positive x-axis. Move an arrow/line clockwise from this axis by 135 degrees. The first 90 degrees are in the bottom right (4th)quandrant. The next 90 degrees(to 180 degrees ; includes 135) will be in the bottom left (3rd) quadrant. NB From the positive x-axis ,moving anti-clockwise about the origin the angles are positive. When moving clockwise from the same axis the angles are negative.
