Answer:
Look at the proof down
Step-by-step explanation:
The given is;
→ ∠1 and ∠2 form a linear pair
→ ∠1 ≅ ∠3
We want to prove;
→ ∠2 and ∠3 are supplementary
<em>We will write the proof in like a table</em>
1. ∠1 and ∠2 formed a linear pair  ⇒  1. Given
2. m∠1 + m∠2 = 180°  ⇒  2. Sum of angles on a straight line
3. ∠1 and ∠2 are supplementary angles  ⇒  3. Supplementary angles add up to 180°
4. ∠1 ≅ ∠3  ⇒  4. Given
5. m∠2 + m∠3 = 180°  ⇒  5. Substitution method
6. ∠3 is a supplement of ∠2  ⇒  6. Supplement of equal angles
7. ∠2 and ∠3 are supplementary  ⇒  7. Proved
