Четырёхугольник \(ABCD\) — прямоугольник. Укажи вектор, равный вектору: 1) \(\vec{AB}\) ; 2) \(\vec{BA}\) ; 3) \(\vec{OC}\) ; 4) \(\vec{OA}\) .

Ответ:

1. \(\vec{AB}=\) \(\mathrlap{\vec{\phantom{ \raisebox{1.1em}{\kern{3.1em}}}}}{\phantom{}}\) [ ];

2. \(\vec{BA}=\) \(\mathrlap{\vec{\phantom{ \raisebox{1.1em}{\kern{3.1em}}}}}{\phantom{}}\) [ ];

3. \(\vec{OC}=\) \(\mathrlap{\vec{\phantom{ \raisebox{1.1em}{\kern{3.1em}}}}}{\phantom{}}\) [ ];

4. \(\vec{OA}=\) \(\mathrlap{\vec{\phantom{ \raisebox{1.1em}{\kern{3.1em}}}}}{\phantom{}}\) [ ].
