How many times does it need to be proven? Doesn't it get a little redundant after a while?

I will do this in paint. It will take a while

Let <span class="math">a, b \in V[/spoiler], and <span class="math">\|\cdot\|[/spoiler] be the euclidean 2-norm. Then
<div class="math">\|a+b\|^2 = \|a\|^2 + 2 \langle a, b\rangle + \|b\|^2</div>
Now if a and b are orthogonal with respect to the standard scalar product, one gets
<div class="math">\|a+b\|^2 = \|a\|^2 + \|b\|^2</div>
which is the pythagorean theorem.
