Any object can be rotated in both directions ie., Clockwise and Anticlockwise directions. 90 CLOCKWISE ROTATION HOW TORotate a square matrix in clockwise directionĪs you can see in the above image we rotate each square in the top cycle and then move to the inner cycle. This video reviews how to perform 90 degree rotations (clockwise and counterclockwise) around the origin.Purchase Transformations Workbook at the following l. How do you calculate a 90 degree rotation The general rule for rotation of an object 90 degrees is (x, y) > (-y, x). Let’s understand the rotation of 90 degrees clockwise about a point visually. If there are inner cycle then repeat the same for them. What is a 90 degree rotation clockwise Answer: To rotate the figure 90 degrees clockwise about a point, every point (x,y) will rotate to (y, -x). It is similar like rotating a gear lock in one direction, first rotate the first layer, then second layer and so on. Traverse half the size of the matrix and in each loop rotate the element by updating them in clock wise or anti-clockwise direction. Run a loop to traverse the matrix a cycle at a time, i.e loop from 0 to N/2 – 1. Swap the elements of the first column with the last column. Rotates the matrix in Clockwise and Counterclockwise as per requirement. Rotate Matrix 90 Degree Clockwise or Right Rotation First, find the transpose of the given matrix. Rotates the matrix by 90, 180 degrees as per requirement. rot90 will be used which is a built-in function. There is N/2 squares or cycles in a matrix of size N. Clockwise
