The coordinates of a quadrilateral are (1, 2), (4, 2), (1, 4), and (4, 4). after a transformation, the new coordinates are (1, −2), (4, −2), (1, −4), and (4, −4). which transformation occurred?

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
