PLEASE HELP! I WILL MARK YOU AS BRAINLIEST IF ANSWERED CORRECTLY! A student was asked to describe a sequence of transformations that maps DEF to D'E'F', given that DEF is equal to D'E'F. She incorrectly said the sequence of the transformations that maps DEF onto D'E'F' is a reflection across the x-axis, followed by a translation of 6 units right and 4 units up. What mistake did the student likely make?

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
