Parallelogram rule for vector addition | Vectors | Precalculus | Khan Academy

The parallelogram rule says that if we place two vectors so they have the same initial point, and then complete the vectors into a parallelogram, then the sum of the vectors is the directed diagonal that starts at the same point as the vectors.

Brilliant explanation! This is exactly what I'm looking for! Thank you so much!

You know they say "The shortest distance between two points is a straight line" so in the parallelogram shape you draw side a + side b will not equal the diagnoal c, but the diagnoal c bisects the parallelogram into 2 traingles so c can be calculated using the Pythagoras theorem c^2=a^2+b^2

This is exactly what my coaching teacher taught me

I feel like I'm forgetting something but imagine an atom. So this I think confirms nothing is the same in other star systems. I find it only objectively true. Also, it's useful for zirconium flame measurements for rocket fuel.

I’m not here for school I’m here because my friend said that she is simping for the man in the video trying to prove her wrong but then I was proved wrong
Edit: she meant only his voice
