Question 738329: Statement: ∠a and ∠b are supplementary angles
∠c and ∠d are supplementary angles
Question: What is the reason for this statement?
Mutiple choices: 1) definition of supplementary angles.
2) If two angles are congruent and form a linear pair, they are right angles.
3) All right angles are congruent
4) If two angles form a linear pair, they are supplementary angles.
Additional information: Given: ∠a ≅ ∠d
Prove: ∠b ≅ ∠c
