George is using the figure below to prove that corresponding angles, 23 and 27, are congruent.
14
He used the Linear Pair Postulate to determine m26 + m27 = 180 and the Same Side Interior Angle Theorem
to determine m23 + m26 = 180°
What could be the next valid step in his proof?
A. Say that m26 + m27 = m23 + m26 because of the Transitive Property.
B. Say that mZ6 + m27 = m23 + m26 because of the Angle Addition Postulate.
C. Say that m23 + m26 + m27 = 180 because of the Angle Addition Postulate.
O D. Say that m23 + m26 + m27 = 180 because of the Definition of Supplementary Angles.
