Fill in the statement for number 4.

• $m\angle ABC=m\angle1+m\angle2$
  $m\angle EFG=m\angle3+m\angle4$
  

• $m\angle ABC=m\angle1+m\angle4$
  $m\angle EFG=m\angle3+m\angle2$
  

• $\angle ABC=\angle1+\angle2$
  $\angle EFG=\angle3+\angle4$
  

• $\angle ABC=\angle1+\angle4$

What does the Definition of Angle Congruence say?

• Angle A is congruent to angle B.

• If a=b, then a+c=b+c.

• If angle A is congruent to angle B, then the measure of angle A is equal to the measure of angle B.

• If a=b, then b=a.
