<span>Suppose a triangle had two right angles.
The sum of all angles of any triangle is 180</span>°.
The measure of a right angle is 90°.
By difference, the measure of the other angle can be determined.
Since the two angles have a measure of 90° each, then by difference, the measure of the third angle is 180° - (90° + 90°) = 0°.
If the angle is 0°, there would only be two sides.
A triangle has three sides.
Therefore, a triangle can't have two right angles.

I think you mean in terms of 
?
Recall Euler's identity
and de Moivre's theorem
where 
.
It follows that
By the binomial theorem, expanding the right side gives
and so
We can factorize this as
and using the Pythagorean identity
this reduces to
