Question

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

Can two obtuse angles be adjacent angles?

Answer 1

If the sum of $2$ angles is less than ${360}^o$, then they can be adjacent.

$\Rightarrow$ Since an obtuse angle is less than ${180}^o$, the sum of $2$ obtuse angles will always be less than ${360}^o$.

Hence, two obtuse angles can be adjacent angles.

$\therefore$ The answer is $1.$
