A trapezium is divided into four triangles by its diagonals.
Suppose the two triangles containing the parallel sides have areas

Three rods of different lengths form three sides of an enclosure
with right angles between them. What arrangement maximises the area
The diagonals of a trapezium divide it into four parts. Can you
create a trapezium where three of those parts are equal in area?
