WebVectors a and b are always right angles to each other, so you can use the Pythagorean theorem to determine the magnitude (or length) of a+b. It is true that the angles between a and a+b or b and a+b can be any angle between (but not including) 0 and 90 degrees, but that doesn't matter when calculating the Pythagorean theorem.
