![]() ![]() Solution: As we know, 180° clockwise and counterclockwise rotation for coordinates (x, y) results in the same, (-x, -y). ![]() Show the plotting of this point when it’s rotated about the origin at 180°. It will look like this:Įxample 3: In the following graph, a point K (-3, -4) has been plotted. So, for this figure, we will turn it 180° clockwise. Solution: We know that a clockwise rotation is towards the right. The images are represented in the following graph.Įxample 2: In the following image, turn the shape by 180° in the clockwise direction. Thus, for point B (4, 3), 180° clockwise rotation about the origin will give B’ (-4, -3). Similarly, for B (4, 3), 90° clockwise rotation about the origin will give B’ (3, -4).ī) For clockwise rotation about the origin by 180°, the coordinates (x, y) become (-x, -y). Common rotation angles are \(90^\) anti-clockwise : (-6.Example 1: Find an image of point B (4, 3) that was rotated in the clockwise direction for:Ī) As we have learned, 90° clockwise rotation about the origin will result in the coordinates (x, y) to become (y, -x). Rotation can be done in both directions like clockwise and anti-clockwise. As a convention, we denote the anti-clockwise rotation as a positive angle and clockwise rotation as a negative angle. The amount of rotation is in terms of the angle of rotation and is measured in degrees. ![]() The point about which the object is rotating, maybe inside the object or anywhere outside it. The direction of rotation may be clockwise or anticlockwise. Thus A rotation is a transformation in which the body is rotated about a fixed point. In the mathematical term rotation axis in two dimensions is a mapping from the XY-Cartesian point system. The rotation transformation is about turning a figure along with the given point. The point about which the object rotates is the rotation about a point. The rotations around the X, Y and Z axes are termed as the principal rotations. In three-dimensional shapes, the objects can rotate about an infinite number of imaginary lines known as rotation axis or axis of motion. It is possible to rotate many shapes by the angle around the centre point. Rotation means the circular movement of somebody around a given centre. Thus, in Physics, the general laws of motions are also applicable for the rotational motions with their equations. But, many of the equations for the mechanics of the rotating body are similar to the linear motion equations. Rotational motion is more complex in comparison to linear motion. Such motions are also termed as rotational motion. Also, the rotation of the body about the fixed point in the space. The motion of some rigid body which takes place so that all of its particles move in the circles about an axis with a common velocity. This article will give the very fundamental concept about the Rotation and its related terms and rules. In geometry, four basic types of transformations are Rotation, Reflection, Translation, and Resizing. In our real-life, we all know that earth rotates on its own axis, which is a natural rotational motion. It is applicable for the rotational or circular motion of some object around the centre or some axis. The term rotation is common in Maths as well as in science.
