Question

Triangle QRS is rotated 180° about the origin. On a coordinate plane, triangle Q R S has points (negative 4, 1), (negative 4, 4), (2, 1). What are the coordinates of point S'? (2, 1) (1, –2) (–1, –2) (2, –1)

Answer 1

1,-2 did it right

Explanation:

Answer 2

(-2,-1)

Explanation:

Given

`Q =(-4,1)`

`R = (-4,4)`

`S = (2,1)`

180 degrees rotation

Required

Determine the coordinate point S'

For a 180-degree rotation, the transformation rule is: (x, y) to (-x, -y)

So:

`S = (2,1)` ==>
`S' = (-2,-1)`

Hence, the coordinate point of S' is (-2,-1)
