Triangle XYZ is transformed to create triangle X'Y'Z'. The side lengths of both triangles are shown.

Side length X Y = 10 cmSide length X prime Y prime = 10 cm

Side length Y Z = 9 cmSide length Y prime Z prime = 9 cm

Side length Z X = 4 cmSide length Z prime X prime = 4 cm

Is this a rigid transformation? Explain.

Yes, the pre-image and image have the same side length measures.
Yes, all transformations are rigid.
No, the side lengths of triangle XYZ are different from each other.
No, each side length of X'Y'Z' should be one half of the corresponding side length of XYZ.
