Abstract

In the July 2009 issue of Learning and Teaching Mathematics (see [1]), I described a proof without words of the area of a trapezium. Unfortunately, due to the given diagram being a special, symmetrical case rather than a general trapezium, some readers might have misinterpreted that the proof was only valid for an isosceles trapezium (see [2]). To clarify this point, we can refer to the visual proofs for two general trapeziums below.
