WebNow for a right triangle, $2$ of the vectors must be orthogonal. The easiest way to test this is to take the dot product. Two vectors are orthogonal if their dot product is $0$. In this case $$\vec{A}\cdot\vec{C}=3(2)+(-2)(1)+1(-4)=0$$ So vectors $\vec{A}$ and $\vec{C}$ form a right angle. So they do in fact form a right triangle.
