provide reasons for the proof. given: ∠2 ≅ ∠4 and ∠2 and ∠3 are supplementary prove: ∠1 ≅ ∠3

7.By transitive property of equality

8.By substitution property

9.Subtraction property of equality

10.Converse of angles congruence postulate.

Step-by-step explanation:

We are given that

, angle 2 and angle 3 are supplementary and angle 1 and angle 4 are supplementary.

We have to prove that

We have to write missing statements in given proof.

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
