describe the transformation that maps ∆ABC onto ∆XYZ.

To describe the transformation that maps ∆ABC onto ∆XYZ, we need to identify the specific type of transformation applied: translation, rotation, reflection, dilation, or a combination of these. Without any additional information or instructions, it is not possible to determine the exact transformation between the two triangles.

However, I can guide you on how to determine the transformation with more details or specific instructions.

no idea, but probably a translation, rotation, or dilation
