Question

what is 270 degree counterclockwise rotation rule? type your answer here open - ended question

Explanation:

Step1: Recall rotation rule

For a 270 - degree counter - clockwise rotation about the origin in a coordinate plane, if a point has coordinates $(x,y)$, the new coordinates $(x',y')$ are given by the transformation $(x,y)\to(y, - x)$.

Answer:

For a point $(x,y)$ in the coordinate plane, a 270 - degree counter - clockwise rotation about the origin gives the point $(y,-x)$.
