Consider △jkl and △mnp.
which statement is true?

the triangles are congruent because there is a series of rigid motions that maps △jkl to △mnp.

the triangles are not congruent because mapping △jkl to △mnp by using only one transformation is not valid.

the triangles are not congruent because at least one of the transformations that map △jkl to △mnp is not a rigid motion.
