Work out where the pieces land after a fold, cut or stack.
In this one. A line of symmetry is a fold line that makes every point on one side match a point on the other.
Words like 'folded', 'cut along the dotted line' or 'stacked' appear beside a shape, and the question asks for a length or angle that only makes sense once the pieces are in their new positions.
Children try to calculate the answer before working out where the pieces actually end up, skipping the visualisation step that the whole question depends on.
