in the line.

The single transformation that fully maps triangle A onto triangle B is the reflection of triangle A across the line y = x

Step-by-step explanation:

The coordinates of the vertices of triangle A are

1) (4, -1)

2) (1, -3)

3) (4, -3)

The coordinates of the vertices of triangle B are

1) (-1, 4)

2) (-3, 1)

3) (-3, 4)

Therefore, we have the points (x, y) in triangle A becoming the points (y, x) in triangle B, which is a reflection across the line y =x.

Hence, the single transformation that fully maps triangle A onto triangle B is the reflection of triangle A across the line y = x.
