A quadrilateral with exactly one pair of opposite sides parallel.
Revise: Quadrilaterals and PolygonsA trapezium has exactly one pair of opposite sides parallel. The other two sides need not be equal, and its diagonals have no general equal-length or bisection rule.
A quadrilateral with exactly one pair of parallel opposite sides.
For a trapezium, add the lengths of the parallel sides before multiplying by the height and halving.
For a trapezium, identify the two parallel sides before using .

A four-sided shape with one pair of parallel sides.
Revise: Gradients and AreasA curved boundary does not usually make an exact triangle or trapezium. At this level, estimate its area without calculus by replacing short pieces of the curve with straight lines. Divide the horizontal interval into equal strips, read the heights at the strip boundaries and treat each strip as a trapezium.
A quadrilateral with one pair of parallel opposite sides.

A four-sided shape with one pair of parallel sides. Under a graph, its parallel sides can be the heights measured at the ends of a time interval.
Revise: Area Under GraphsIf speed changes, the region may instead be a triangle, a trapezium or a curved shape, but its area still gives distance travelled.
A four-sided shape with one pair of parallel opposite sides.
For a curved graph, show the strip widths and endpoint heights used in each trapezium.
