Question

Two angles forming a linear pair are
supplementary
comlementary
vertically opposite

Answer 1

Answer:

Two angles forming a linear pair are  supplementary

Answer 2

$\huge {\underline \blue{A}}{\underline \purple{n}}{\underline \pink{s}}{\underline \green{w}}{\underline \red{e}}{\underline \orange{r}} -$

→∠1 and ∠2 are supplementary. If two angles form a linear pair, the angles are supplementary. A linear pair forms a straight angle which contains 180º, so you have 2 angles whose measures add to 180, which means they are supplementary.
