![]() That and it looks like it is getting us right to point A. Our center of rotation, this is our point P, and we're rotating by negative 90 degrees. Which point is the image of P? So once again, pause this video and try to think about it. Than 60 degree rotation, so I won't go with that one. And it looks like it's the same distance from the origin. Like 1/3 of 180 degrees, 60 degrees, it gets us to point C. So does this look like 1/3 of 180 degrees? Remember, 180 degrees wouldīe almost a full line. How do you rotate a figure 90 degrees in clockwise direction on a graph Rotation of point through 90° about the origin in clockwise direction when point M (h, k) is rotated about the origin O through 90° in clockwise direction. One way to think about 60 degrees, is that that's 1/3 of 180 degrees. Learn about the rules for 90 degree clockwise rotation about the origin. So this looks like aboutĦ0 degrees right over here. It’s a common geometric transformation used in mathematics and graphics to change the orientation of objects or points. This results in a right angle, where two lines or line segments meet to form an L shape. P is right over here and we're rotating by positive 60 degrees, so that means we go counterĬlockwise by 60 degrees. A 90-degree angle rotation involves turning an object or point counterclockwise by 90 degrees. It's being rotated around the origin (0,0) by 60 degrees. Which point is the image of P? Pause this video and see That point P was rotated about the origin (0,0) by 60 degrees. I included some other materials so you can also check it out. Rotating 90 degrees clockwise is the same as rotating 270 degrees counterclockwise. ![]() ![]() There are many different explains, but above is what I searched for and I believe should be the answer to your question. All the rules for rotations are written so that when youre rotating counterclockwise, a full revolution is 360 degrees. There is also a system where positive degree is clockwise and negative degree anti-clockwise, but it isn't widely used. Product of unit vector in X direction with that in the Y direction has to be the unit vector in the Z direction (coming towards us from the origin). Clockwise for negative degree.įor your second question, it is mainly a conventional that mathematicians determined a long time ago for easier calculation in various aspects such as vectors.
