كويز تفاعلي: Rotations

Geometric rotations are transformations that turn a figure around a fixed point, known as the center of rotation. In the coordinate plane, the origin (0, 0) is often used as this center. Common rotations include 90, 180, and 270 degrees. Each rotation follows a specific algebraic rule: for a 90-degree clockwise rotation, (x, y) becomes (y, -x); for a 180-degree rotation, (x, y) becomes (-x, -y); and for a 270-degree clockwise rotation (or 90-degree counterclockwise), (x, y) becomes (-y, x). These transformations preserve the size and shape of the figure while changing its orientation and position within the quadrants.
