Question

PLEASE HELP ASAP!!!!

Which Statement directly describes the relationship between Δ DEF and Δ D'E'F' ?

a. Δ DEF is congruent to Δ D'E'F' Because you can map Δ DEF to Δ D'E'F using a reflection across the y-axis, which is a rigid motion.

b. Δ DEF is not congruent to Δ D'E'F' because there is no sequence of rigid motions that maps Δ DEF to Δ D'E'F'.

c. Δ DEF is congruent to Δ D'E'F' because you can map Δ DEF to Δ D'E'F' using a reflection across the x-axis, which is a rigid motion.

d. Δ DEF is congruent to Δ D'E'F' because you can map Δ DEF to Δ D'E'F' using a rotation of 180° about the origin, which is a rigid motion.

Answer 1

c. △DEF is congruent to △D'E'F' because you can map △DEF to △D'E'F' using a reflection across the x-axis, which is a rigid motion.
