As shown in the figure, ad ∥ BC, EA and EB are equally divided into ∥ DAB, ∥ CBA and CD through point e respectively, and the verification is: ab = AD + BC

If e is taken as EF ‖ AD and ab is crossed with F, then ∠ DAE = ∠ AEF, ∠ EBC = ∠ bef, ∵ EA and EB are divided equally into ∠ DAB and ∠ CBA, ∵ EAF = ∠ AEF, ∵ EBF = ∠ bef, ∵ AF = FB, and ∵ EF ‖ ad ‖ BC, ∵ EF is the median line of trapezoidal ABCD, ∵ EF = AD + BC2, ∵ AF + FB = 2ef, ∵ AB = AD + BC
