Move each point with the coordinates (a, b) to the location (b, -a).Equivalently, if the points are represented by a 2x1 column matrix, then pre-multiply by the matrix

How do you rotate a triangle by 90 degrees clockwise?
rotate it 90 degrees
How do you rotate a figure 270 degrees clockwise about origin?
You dont, its just 90 degrees 3 times..
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.
How do you rotate 90 degrees clockwise?
stick your arms straight out in front of you. Pretend that's twelve o'clock then move one of your arms to three o'clock. Bring the other arm and turn your body to three o'clock. you have just moved 90 degrees clockwise.
How do you rotate a figure 90 degrees clockwise?
Switch the x and y coordinates and multiply the first first coordinate (the new x coordinate) by -1
How do you rotate a triangle by 90 degrees clockwise?
rotate it 90 degrees
How do you rotate a figure 270 degrees clockwise about origin?
You dont, its just 90 degrees 3 times..
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 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 polygon 90 degrees counterclockwise about the origin?
{1 0} {0 -1}
What is (-53) 90 degrees clockwise?
ENE plus 90 degrees (clockwise) is SSE.
How do you rotate a figure 90 degrees counter clockwise about the origin?
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 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."
How do you rotate 90 degrees clockwise?
stick your arms straight out in front of you. Pretend that's twelve o'clock then move one of your arms to three o'clock. Bring the other arm and turn your body to three o'clock. you have just moved 90 degrees clockwise.
How do you rotate shapes 90 degrees clockwise about the origin?
Move each point with the coordinates (a, b) to the location (b, -a).Equivalently, if the points are represented by a 2x1 column matrix, then pre-multiply by the matrix ( 0 1) (-1 0)
How do you rotate an angle 90degree's clockwise?
Imagine a clock: a circle is 360 degrees, so every 5 minutes is 30 degrees. If you started at 1pm and rotated it 90 degrees it would be 1.15pm
