Question

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

Can two right angles be complement to each other?

Answer 1

We know, right angle is the angle equal to ${90}^o$.

Two right angles can never be a complement to each other.
Since the right angle means $90$ degrees, so the sum of two right angles will always be $180$ degrees.

E.g.: Let us suppose two obtuse angles are ${90}^o$ & ${90}^o$.
Here, the sum of these two obtuse angles will give us ${180}^o$.
Since, for being complementary, sum should be equal to ${90}^o$,
we can say that no pairs of right angles are complementary.
Hence, the statement is false and $0$ is the answer.
