$\overrightarrow{AB} = \overrightarrow{BC}$

$\overrightarrow{BC} = \overrightarrow{AD}$

$\overrightarrow{CD} = -\overrightarrow{AB}$

$\left| \overline{AB} \right| = \left| \overline{AD} \right|$

$\vec{0}$

$\overrightarrow{CD}$

$\overrightarrow{CB}$

$\overrightarrow{AD}$

$\overrightarrow{AB} + \overrightarrow{AD} = \overrightarrow{AO}$

$\overrightarrow{AB} - \overrightarrow{AD} = 2\overrightarrow{BO}$

$\overrightarrow{AB} + \overrightarrow{AD} = 3\overrightarrow{GA}$

$\overrightarrow{AB} - \overrightarrow{BC} = \overrightarrow{DB}$

$\vec{a} . \vec{b} = \left| \vec{a} \right| . \left| \vec{b} \right| . \cos \left( \overrightarrow{a,b} \right)$

$\vec{a} . \vec{b} = \left[ \vec{a}.\vec{b} \right] . \cos \left( \overrightarrow{a,b} \right)$

$\vec{a}.\vec{b} = \left| \vec{a} \right| . \left| \vec{b} \right| . \sin \left( \overrightarrow{a,b} \right)$

$\vec{a}.\vec{b} = \left| \vec{a} \right| . \left| \vec{b} \right|$
