brainliest and 20 points! which best explains whether or not δabc ≅ δlmn? the figures are congruent because a 270° rotation about the origin and then a reflection over the x-axis will map δabc onto δlmn. the figures are congruent because a 90 rotation about the origin and then a reflection over the x-axis will map δabc onto δlmn. the figures are not congruent because point b corresponds with point n and point c corresponds with point m. the figures are not congruent because there is no rigid transformation or combination of rigid transformations that will map δabc onto δlmn.
