Triangle jkl is transformed to create triangle j'k'l'. the angles in both triangles are shown. j = 90° j' = 90° k = 65° k' = 65° l = 25° l' = 25° which statement is true about this transformation? it is a rigid transformation because the pre-image and image have the same corresponding angle measures. it is not a rigid transformation because the corresponding side lengths are not equal. it can be a rigid or a nonrigid transformation depending on whether the corresponding side lengths have the same measures. it can be a rigid or a nonrigid transformation because a pair of corresponding angles measures 90°.
