Question

Which statement correctly identifies the line of reflection?

On a coordinate plane, a triangle is reflected across y = x.
The triangles are reflected across the x-axis.
The triangles are reflected across the y-axis.
The triangles are reflected across the line y = x.
The triangles are reflected across the line y = –x.

Answer 1

The statement that correctly identifies the line of reflection when a triangle is reflected across the line \( y = x \) is:

**The triangles are reflected across the line \( y = x \).**

This statement directly describes the line across which the reflection occurs.
