>>12640891Visualise it in your head anon, your sign is the wrong way around
The triangle inequality essential states that for a triangle, the length of the hypotenuse, can only be less than or equal to the length of the other two sides
abs(V-W) is equal to abs(V+W), i.e it is still the length of the hypotenuse. Intuitively we know that the length of the hypotenuse will always be greater than the length of one side subtracted from the length of the other side so your sign is the wrong way round and
>>12641039 is correct
