Question

Triangle TUV has coordinates T(0, 3) , U(−3, 0) , and V(−4, 4) . The triangle is reflected across the y-axis.Write the coordinate notation for a reflection across the y-axis.

Answer 1

To reflect a triangle across the y-axis, flip the sign of the x-coordinate while keeping the y-coordinate the same.

Step-by-step explanation:

Triangle Reflection across the y-axis:

To reflect a point across the y-axis, we simply change the sign of the x-coordinate while keeping the y-coordinate the same.

In this case, we have triangle TUV with coordinates T(0, 3), U(-3, 0), and V(-4, 4).

To reflect these points across the y-axis, we flip the sign of the x-coordinate.

T'(-0, 3), U(3, 0), V(4, 4).
