What is the algebraic rule for a figure that is rotated 270° clockwise about the origin?
Answer: (x, y) → (y, -x)
Algebraic Rules for Rotations
The algebraic rule for a figure rotated 270° clockwise about the origin is (x, y) → (y, -x). This transformation involves switching the x and y coordinates and then changing the sign of the new x-coordinate. Understanding transformations such as rotations is crucial in coordinate geometry and algebra. These concepts are widely used in fields like computer graphics, engineering design, and robotics. Grasping how to apply algebraic rules for geometric transformations enables students and professionals to visualize and manipulate objects in a spatial context.
