Talk:Angle Bisector Vector

First time I've seen this proof. Cool.

We still need to prove that $$|\vec{u}|\vec{v}$$ and $$|\vec{v}|\vec{u}$$ have equal length - we need a separate page for that, I think. Also, I wonder whether, having proved this, one can appeal directly to Euclid to get the rest? --Matt Westwood 19:39, 26 September 2009 (UTC)

Do you think it would be sufficient as a collorary to the length of a vector multiplied by a scalar? --Espen180 14:39, 27 September 2009 (UTC)

Possibly, but if it were me doing it, I'd put it on a on separate page, as that gives us more flexibility of which direction to come at it from. --Matt Westwood 21:28, 27 September 2009 (UTC)

Geometrical proof 2
The case of the rhombus diagonals is a subject which will need coverage in a separate proof.
