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. Comment ( 3 votes) WebIn general, the more two vectors point in the same direction, the bigger the dot product between them will be. When \theta = \dfrac {\pi} {2} θ = 2π, the two vectors are precisely perpendicular to each other. This corresponds to the dot product between them being 0 0, because \cos\left ( \dfrac {\pi} {2} \right) = 0 cos(2π) = 0.
