How to check if these vectors are normal or orthogonal?

$\begingroup$

If we have number of vectors. $a = (1, 0, 2, 0)$ $b = (-2, 1, 0, -1)$ $c = (-1, 1, 2, -1)$

How to check if they are normal, or orthogonal vectors?

Dot Product and Orthogonal Vectors:

Vectors $\vec {a}$ and $\vec{b}$ are orthogonal (or perpendicular) to each other if, $\vec{a} \cdot \vec{b} = 0$.
