In case, there is an object which is rotating that can rotate in different ways as shown below:ģ. 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).

We discuss how to find the new coordinates of. Rule of 90 Degree Rotation about the Origin Learn how to rotate figures about the origin 90 degrees, 180 degrees, or 270 degrees using this easier method. 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.
