Question

when rotated 90°, the points are (0,6),(-2.3,5.5),(-4.2,4.2),(-5.5,2.3) (type ordered pairs. use a comma to separate answers as needed.) when rotated 180°, the points are . (type ordered pairs. use a comma to separate answers as needed.)

Explanation:

Step1: Recall 180 - degree rotation rule

The rule for rotating a point $(x,y)$ 180 degrees counter - clockwise about the origin is $(x,y)\to(-x,-y)$.

Step2: Apply rule to each point

For the point $(0,6)$: $x = 0,y = 6$, so the new point is $(0,- 6)$.
For the point $(-2.3,5.5)$: $x=-2.3,y = 5.5$, so the new point is $(2.3,-5.5)$.
For the point $(-4.2,4.2)$: $x=-4.2,y = 4.2$, so the new point is $(4.2,-4.2)$.
For the point $(-5.5,2.3)$: $x=-5.5,y = 2.3$, so the new point is $(5.5,-2.3)$.

Answer:

$(0,-6),(2.3,-5.5),(4.2,-4.2),(5.5,-2.3)$
