If true then enter $1$ and if false then enter $0$

Can two obtuse angles form a linear pair?

Answer 1

No.

Two obtuse angles can never form a linear pair.
For two angles to form a linear pair, they need to give a sum of 180 degrees.
But obtuse angles are greater than 90 degrees, so two obtuse angles will always give a sum greater than 180 degrees.
