Question

In the given figure, ∠1 and ∠2 are supplementary angles. If ∠1 is decreased, what changes should take place in ∠2 so that both angles still remain supplementary

Answer 1

Answer:

corresponding increase

Step-by-step explanation:

if the two angles are 100 and 80

If the first one decreases by 10, the second one will increase by 10

so both will be 90 and 90..two right angles

Answer 2

Answer:

From the question, it is given that,

∠1 and ∠2 are supplementary angles.

If ∠1 is decreased, then ∠2 must be increased by the same value. Hence, this angle pair remains supplementary.
