It has been bothering me alot. Clockwise vs. Counterclockwise Rotations If a point is rotating 90 degrees clockwise about the origin our point M(x,y) becomes M'(y,-x). Math. A rotation maps every point of a preimage to an image rotated about a center point, usually the origin, using a rotation matrix. The rotation 90º clockwise matrix is [0 1 / -1 0]. Save. All four triangles are congruent, because they are all right-angled triangles and all have two congruent sides. Rotation of point through 90° about the origin in clockwise direction when point M (h, k) is rotated about the origin O through 90° in clockwise direction. Note the corresponding clockwise and counterclockwise rotations. Here, in this article, we are going to discuss the 90 Degree Clockwise Rotation like definition, rule, how it works, and some solved examples. 360 degree rotation. Example: rot90(A,-2) rotates A by -180 degrees and is equivalent to rot90(A,2), which rotates by 180 degrees. Specify k to rotate by k*90 degrees rather than nesting calls to rot90. 90* Counterclockwise C. 180* D. 360* Please help!
