Question
What is the rule for a 180° clockwise rotation?Question 17Select one:a.(x, y) → (-y, -x)b.(x, y) → (y, x)c.(x, y) → (y, -x) d.(x, y) → (-x, -y)
Solution
The rule for a 180° clockwise rotation is (x, y) → (-x, -y). So, the correct answer is option d.
Here's why:
A rotation of 180° about the origin can be seen in the change of sign in both the x and y coordinates. So, if you start with the point (x, y), after a 180° clockwise rotation, the new point would be (-x, -y).
