Как то так..лайк если можно
Объяснение:
Трапеция ABCD, AD II BC; AD > BC (то есть AD = 16; BC = 12)
Средняя линяя равна (12 + 16)/2 = 14. Отрезок средней линии между диагональю АС и боковой стороной АВ равен половине малого основания ВС (то есть 6) - это средняя линяя в треугольнике АВС. Аналогично, отрезок средней линии между диагональю BD и боковай стороной CD тоже равен половине ВС (тоже 6) - это средняя линяя треугольника BCD. Поэтому искомый отрезок средней линии, заключенный между диагоналями, равен 14 - 2*6 = 2.
В общем случае, если основания a > b, то этот отрезок равен (a - b)/2
