Question

Two supporting reasons are missing from the proof. Complete the proof by dragging and dropping the appropriate reasons into each

of the empty boxes
Given
m || n
m∠1 = 120°
Prove m∠6 = 60°

m || n
m∠1 = 120°-given

∠5≈∠1- ?

m∠5= m∠1-angle congruence postulate

m∠5= 120°-substitution property of equality

m∠6+m∠5= 180°- ?

m∠6+120°= 180°-substitution property of equality

m∠6= 60°-subtraction property of equality

Answer 1

∠5≈∠1 - corresponding angles

m∠6+m∠5=180° - supplementary angles

i hope this helps!
