She used the Linear Pair Postulate to
determine mz2+
m23 = 180° and
the Same Side Interior
Angle Theorem
to determine m23
+ m25 = 180°.
What could be the next valid step in
her proof?
A. Say that
cano อมา
mz2+m23+ m25 = 180°
because of the Definition of
Supplementary Angles
B. Say that
mz2+mz3+m25 = 180°
because of the Angle
Addition Postulate
C. Say that
mz2+mz3 = m23+m25
because of the Angle
Addition Postulate
D. Say that
mz2+m23 = m 23+ m25
because of the Transitive
