WebThe triangle inequality theorem states that, in a triangle, the sum of lengths of any two sides is greater than the length of the third side. Suppose a, b and c are the lengths of the sides of a triangle, then, the sum of lengths of a and b is greater than the length c. Similarly, b + c > a, and a+ c > b. If, in any case, the given side lengths ...
WebSep 29, 2024 · Proof 3. Let z1 and z2 be represented by the points A and B respectively in the complex plane . From Geometrical Interpretation of Complex Addition, we can construct the parallelogram OACB where: OC represents z1 + z2. As OACB is a parallelogram, we have that OB = AC .
