I hope this stuff helps, as confusing as some of this might be. The best way I can explain it is that I take a 1:1 reverser linkage (360 degrees clockwise input produces 360 degree counterclockwise output), anchoring the input into place, then spinning the whole machine, which basically changes the frame of reference and allows for 1:2 conversion. Īnother method for a 360 degree linkage is to get a 180 degree linkage (you can find it in Episode 2 of The Kinetic Bridge Basics) and then creating a 1:2 converter, though the current ones I have invented so far are incredibly ridiculous I can't exactly give you a reasonable tutorial on them. Draw on a white board or on a piece of paper P'., Rotate shape R around the center point 180. Draw on a white board or on a piece of paper P'., Rotate figure P around the origin 180 degrees. Draw on a white board or on a piece of paper Q'., Rotate P 90 degrees counterclockwise around the origin. To brace it takes a lot though (bottom linkage), so only use it if you really must. Rotate Q 270 clockwise degrees around the center. The easiest one I could find is this one which is popcorniosaurus's 360 linkage (top linkage) which looks simple but is extremely unstable. there's a lot of them out there and it's incredibly difficult to actually explain some of them. To describe a rotation, you need three things: Direction (clockwise CW or counterclockwise CCW) Angle in degrees Center point of rotation (turn about what point) The most common rotations are 180° or 90° turns, and occasionally, 270° turns, about the origin, and affect each point of a figure as follows: Rotations About The Origin 90 Degree. The green bar rotates 270 degrees (I finally got my colored materials mod working again) Īs for a 360 degree linkage. The algebraic rule for a figure that is rotated 270° clockwise about the origin is (y, -x).Here are three (technically 2) designs you can use! I recommend the bottom left one because it's a good balance between sturdy and consistent. Therefore, the algebraic rule for a figure that is rotated 270° clockwise about the origin is (y, -x) Therefore, the coordinate of a point (3, -6) after rotating 90° anticlockwise and 270° clockwise is (-6, -3). Rotating 270° clockwise, (x, y) becomes (y, -x) Rotating 90° anticlockwise, (x, y) becomes (-y, x) Almost certainly your 3-year-old accidentally pressed Ctrl-Alt, and some arrow key. Given, the coordinate of a point is (3, -6) Is there > a way to get the screen to return to normal The ability to rotate the screen image is a feature of your video card, to help it work with monitors that rotate to portrait orientation. ![]() What will be the coordinate of a point having coordinates (3,-6) after rotations as 90° anti-clockwise and 270° clockwise? Rotating a figure 270 degrees clockwise is the same as rotating a figure 90 degrees counterclockwise. In your final answer, name the equivalent counterclockwise rotation and show all of your work. Given parallelogram PARK.Prove graphically and algebraically that a clockwise rotation of 270o about the origin has an equivalent counterclockwise rotation. ![]() The amount of rotation is called the angle of rotation and it is measured in degrees. In your final answer, name the equivalent. ![]() The fixed point is called the center of rotation. What is the algebraic rule for a figure that is rotated 270° clockwise about the origin?Ī rotation is a transformation in a plane that turns every point of a preimage through a specified angle and direction about a fixed point.
