Below is how the formula for the 180-degree rotation of a given point is represented.įor example, the table below shows the original position of points on a coordinate system and the rotated position through 180 degrees. If P (x, y) is a point that must be rotated 180 degrees about the origin, the coordinates of this point after the rotation will only be of the opposite signs of the original coordinates. A graph is used to illustrate the transformation visually. If a closed figure is rotated through 180 degrees, the vertices of the original figure will then be considered to identify the new position of the vertices after rotation. When this occurs, the new position of point P ( x, y ), denoted by the symbol P’, is (-x, -y).

When rotated with respect to the origin, which acts as the reference point, the angle formed between the before and after rotation is 180 degrees.Ī point can be rotated by 180 degrees, either clockwise or counterclockwise, with respect to the origin (0, 0). What is 180 Degree Rotation? DefinitionĪ 180-degree rotation transforms a point or figure so that they are horizontally flipped. The graph before and after the rotation will also be displayed. We will learn more about the 180-degree rotation of a point and a closed figure in this article. One of the simplest and most common transformations in geometry is the 180-degree rotation, both clockwise and counterclockwise. You can rotate a figure either clockwise or counterclockwise. The shape and dimensions of a figure remain the same while facing in a different direction. An example of a transformation is a rotation, which revolves a figure around a point. The most prevalent example is the earth, which revolves around an axis.
