Two lines are parallel if they are straight lines that are always the same (non-zero) distance apart.

Parallel vectors in algebraic vector notation

Maths

In the prior unit, pupils described a translation using column vector notation. Pupils' understanding of vectors is further developed in this unit, with pupils exploring column vector notation and arithmetic procedures.

Vectors

Select the correct statements for parallel vectors. Parallel vectors __________.

Which of these vectors are parallel to $${4 \choose -3}$$?

Which of these vectors are parallel to $$3\mathbf{a}+5\mathbf{b}$$?

Match each vector to a vector that is parallel to it.

$$\frac{1}{2}\overrightarrow{AB}=\overrightarrow{MN}$$

$$2\overrightarrow{MN}=\overrightarrow{AB}$$

$$\frac{1}{3}\overrightarrow{AB}=\overrightarrow{MN}$$

$$3\overrightarrow{MN}=\overrightarrow{AB}$$

OACB is a parallelogram. M is the midpoint of OA and N is the midpoint of OB. $$\overrightarrow{OM}=10\mathbf{a}$$ and $$\overrightarrow{ON}=10\mathbf{b}$$. Select the correct scalar multipliers.

$$\overrightarrow{XY} = \overrightarrow{WZ}$$

$$\overrightarrow{YC} = \overrightarrow{ZD}$$

$$\overrightarrow{AX} = \overrightarrow{AW}$$

$$\overrightarrow{XW} = \overrightarrow{YZ}$$

ABCD is a kite. AX:XB = 1:1, BY:YC = 1:1, DZ:ZC = 1:1 and AW:WD=1:1,  $$\overrightarrow{AW}= 3\mathbf{a}$$, $$\overrightarrow{AX}=3\mathbf{b}$$ and $$\overrightarrow{DZ}=3\mathbf{c}$$.

Parallel vectors must be in the same direction.

Parallel vectors can have different magnitudes.

Parallel vectors may have opposite directions.
