the rule (x, y) + (-x, y) maps a abc to a a'b'c'.
which statement correctly describes the relationship between a abc and a abc?
the triangles are not congruent because a a'b'c' is a translation of a abc, and a
translation is not a rigid motion.
o
the triangles are congruent because a a'b'c' is a reflection of a abc , and a
reflection is a rigid motion

fil-
the triangles are not congruent because a a'b'c' is a reflection of a abc,
reflection is not a rigid motion.
the triangles are congruent because a a'b'c' is a rotation of a abc, and a rotation
is a rigid motion.
