Triangle xyz is transformed to create triangle x'y'z'. the side lengths of both triangles are shown. = 10 cm = 10 cm = 9 cm = 9 cm = 4 cm = 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.

( a ) is the correct answer to the question.

yes, the pre-image and image have the same side length measures.

explanation:

a rigid transformation is one in which congruence is preserved.   this means that the angle measures and side lengths of the pre-image do not change in the image.

comparing the side lengths, we can see that they are the same from the pre-image to the image; this means that this is congruent and this is a rigid transformation.
