Question

The triangle STU shown on the coordinate grid below is reflected once to map onto triangle S'T'U':

If vertex T' is at (2, -2), what are the coordinates of vertex S'?

(6, -8)

(-6, 8)

(8, -6)

(-8, 6)

Answer 1

From the image first determine the coordinates of points T and S.
What is the coordinate of point T?
What is the coordinate of point S?

Answer 2

T (2,2) and S (8,6).. right?

Answer 3

since The y value changed sign going from T to T'
so from S to S' you will get (8, -6).

Answer 4

Thanks... So it won't go to (-8, -6) it'll just be (8, -6)?

Answer 5

T(2,2) and T'(2,-2)
Only the y-coordinate has changed sign which implies reflection about the x-axis.
Therefore, S(8,6) will become S'(8,-6).

Answer 6

yeah true...!!!
