Doing it with linear algebra is a good way to learn linear algebra basics. Calculations. Now lets apply the rule to the coordinates of the vertices of PQRS. You can also use the Quick Links dropdown above to jump to a section of your choice. Then we can join the points and find the new positioned figure. Therefore, kite KLMN was rotated 180 about the origin to create kite KLMN. Rotating a point that has the coordinates \((x,y)\) 90 about the origin in a clockwise direction produces a point that has the coordinates \((y,-x)\). If you take a coordinate grid and plot a point, then rotate the paper 90 or 180 clockwise or counterclockwise about the origin, you can find the location of the rotated point.

The clock reads 12:10 pm. Rotation of a point through 180, about the origin when a point M (h, k) is rotated about the origin O through 180 in anticlockwise or clockwise direction, it takes the new position M (-h, -k). The rule is for h, x y, coordinate, we're going to take the opposite of y and put it in x and leave y alone, but put it in is spot. Here is a figure rotated 90 clockwise and counterclockwise about a center point. The angle of rotation is usually measured in degrees. Half of 180 degrees is 90 degrees, and 90 degree angles are easy to spot. 180 Degree Rotation. The shape of the layer is not altered, but the rotation may cause the layer to extend beyond the bounds of the image. So the cooperative anticlockwise implies positive sign magnitude.There are specific clockwise and the Lets look at a real example, here we plotted point A at (5,6) then we rotated the paper 90 clockwise to create point A, which is at (6,-5).
