<h2>Solving the Question</h2>
We're given:
In a trinomial, we're given the
and
values. <em>a</em> in this case is 1 and <em>b</em> in this case is 4. To find the third value by dividing 4 by 2 and squaring the quotient:
Therefore, the term that we can add is + 4.

To write this as the square of a bracketed expression, we can follow the rule
:

<h2>Answer</h2>


I and III seem to be correct, II doesn't because, for example, if x = w = z = t = 70 and y = u = 40, then all three pairs of vertical angles in the figure have equal measure and the given condition x + y = u + w stands. But it means y is not equal to w.
