Question

in the figure, ∠1 and ∠2 are supplementary angles.
if ∠1 decreases, what changes should take place so that both the angles still remain supplementary?

Answer 1

Answer:

you need to send the pic so I can understand what the question actually is. But I still try.

Step-by-step explanation:

If angle 1 = 80°

angle 2 = 100°

If angle 1 is decreased by 10° i.e. 70°

angle 2 will increase by 10° i.e. 110°

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.
