To find the coordinates of the vertices of ΔS’T’U’ after reflecting ΔSTU over the y-axis, we need to change the sign of the x-coordinates of the points S, T, and U while keeping the y-coordinates the same.
Assuming the original coordinates are:
– S(x₁, 3)
– T(x₂, -1)
– U(x₃, -3)
After reflection over the y-axis, the new coordinates will be:
– S'(-x₁, 3)
– T'(-x₂, -1)
– U'(-x₃, -3)
Since you provided the coordinates for S’, T’, and U’:
– S'( , 3)
– T'( , -1)
– U'( , -3)
You just need to replace the blanks with the opposite signs of the original x-coordinates.
If you can provide the original coordinates for S, T, and U, I can give you the exact coordinates of S’, T’, and U’. Otherwise, follow the explanation to find the reflected points based on your original coordinates!
