Question

transformations > rotations imagine a counterclockwise rotation of 270° about the origin of the figure. choose the coordinate of a. (1 point) (-1,-2) (1,1) (2,-1) (1,2)

Explanation:

Step1: Recall rotation rule

The rule for a counter - clockwise rotation of 270° about the origin is $(x,y)\to(y, - x)$.

Step2: Identify coordinates of A

The coordinates of point A are $(-2,1)$.

Step3: Apply rotation rule

Using the rule $(x,y)\to(y, - x)$ with $x=-2$ and $y = 1$, we get $(1,2)$.

Answer:

$(1,2)$
