#270 ROTATION RULE FOR GEOMETRY FULL#

The rotated triangle will be called triangle A'B'C'. The point at which we do the rotation, we'll call point P. Well, let's say the shape is a triangle with vertices A, B, and C, and we want to rotate it 90 degrees. The shape is being rotated! But how do we do this for a specific angle? With your finger firmly on that point, rotate the paper on top. Now place your finger on the rotation point. Put another paper on top of it (I like to imagine this one as being something like a transparent sheet protector, and I draw on it using a dry-erase marker) and trace the point/shape. Here's something that helps me visualize it: The 'formula' for a rotation depends on the direction of the rotation. I'm sorry about the confusion with my original message above. If you want to do a clockwise rotation follow these formulas: 90 = (b, -a) 180 = (-a, -b) 270 = (-b, a) 360 = (a, b). Also this is for a counterclockwise rotation.

360 degrees doesn't change since it is a full rotation or a full circle. 180 degrees and 360 degrees are also opposites of each other. So, (-b, a) is for 90 degrees and (b, -a) is for 270. In case, there is an object which is rotating that can rotate in different ways as shown below:ģ.The way that I remember it is that 90 degrees and 270 degrees are basically the opposite of each other. You can see the rotation in two ways ie., clockwise or counterclockwise. Is a 90 Degree rotation clockwise or counterclockwise?Ĭonsidering that the rotation is 90 Degree, you should rotate the point in a clockwise direction. I believe that the above graph clears all your doubts regarding the 90 degrees rotation about the origin in a clockwise direction. The rule/formula for 90 degree clockwise rotation is (x, y) -> (y, -x).Īfter applying this rule for all coordinates, it changes into new coordinates and the result is as follows: Next, find the new position of the points of the rotated figure by using the rule in step 1.įinally, the Vertices of the rotated figure are P'(3, 6), Q’ (6, -9), R'(7, -2), S'(8, -3).įind the new position of the given coordinates A(-5,6), B(3,7), and C(2,1) after rotating 90 degrees clockwise about the origin? In step 1, we have to apply the rule of 90 Degree Clockwise Rotation about the Origin Now, we will solve this closed figure when it rotates in a 90° clockwise direction, If this figure is rotated 90° about the origin in a clockwise direction, find the vertices of the rotated figure. Let P (-6, 3), Q (9, 6), R (2, 7) S (3, 8) be the vertices of a closed figure. (iii) The current position of point C (-2, 8) will change into C’ (8, 2) (ii) The current position of point B (-8, -9) will change into B’ (-9, 8) (i) The current position of point A (4, 7) will change into A’ (7, -4) When the point rotated through 90º about the origin in the clockwise direction, then the new place of the above coordinates are as follows: Solve the given coordinates of the points obtained on rotating the point through a 90° clockwise direction?

When the object is rotating towards 90° anticlockwise then the given point will change from (x,y) to (-y,x).

When the object is rotating towards 90° clockwise then the given point will change from (x,y) to (y,-x).

Rule of 90 Degree Rotation about the Origin In short, switch x and y and make x negative. If a point is rotating 90 degrees clockwise about the origin our point M(x,y) becomes M'(y,-x). So, Let’s get into this article! 90 Degree Clockwise Rotation

Here, in this article, we are going to discuss the 90 Degree Clockwise Rotation like definition, rule, how it works, and some solved examples. 90° and 180° are the most common rotation angles whereas 270° turns about the origin occasionally. However, Rotations can work in both directions ie., Clockwise and Anticlockwise or Counterclockwise. If we talk about the real-life examples, then the known example of rotation for every person is the Earth, it rotates on its own axis.

A Rotation is a circular motion of any figure or object around an axis or a center. In Geometry Topics, the most commonly solved topic is Rotations.
