So far, i have
b. Supp. postulate
c. Supp. definition
e. congruence postulate
g. im not sure but i believe its same-side interior angle postulate
and i have no clue what h is.
help on g and h plz

 

[fasteddie65]

f should be "m1 + m3 = 180".
g reason: substitution
h reason: if same-side interior angles are supplementary, then the lines are parallel.

 

[lectromagnet94]

f is written as m3+m2=180
sorry for confusion
