Which of the following sentences are statements? Justify
(i) A triangle has three sides.
(ii) 0 is a complex number.

(i) A statement is a declarative sentence if it is either true or false but not both.

Hence, it is a true statement

(ii) If a statement is true or false but not both, it is a declarative sentence.

As a result, the statement “0 is a complex number” is correct. Because a+ib, where the imaginary portion is 0, can be written as a+0i.

As a result, it is correct.
