Given any triangle in the plane, associate to each side an outward pointing normal vector of the same length as the side. Show t

Zigmanuir [339]

Let , a, b and c be the length of three sides of triangle, represented in terms of vectors as $\vec{a},\vec{b},\vec{c}$ .

Now, vector of same Magnitude acts as normal vector to each side.

So, equation of any vector p having normal q is given by

$\vec{p} \times\vec{q}$

Now sum of three vector and it's normal is given as

$=\vec{a} \times\vec{a}+\vec{b} \times\vec{b}+\vec{c} \times\vec{c}\\\\=0+0+0\\\\=0$

Cross product of two identical vectors is Zero.

$\rightarrow \vec{i} \times\vec{i}=0$
