Problem Solving using Vectors (AQA A-Level Mathematics): Flashcards

Equal vectors, e.g. $\overrightarrow{BC} = \overrightarrow{AD}$

Vectors in same direction, multiples of each other

Two pairs of parallel sides and right angles

Two pairs of parallel sides

Four sides of the same length

All four sides equal length and all angles 90°

$\overrightarrow{BC} = C - B$

Show opposite sides are equal vectors

Product of gradients = $-1$

Product of gradients $\neq -1$
