The diagonal of a trapezoid divides it into two triangles.

Conditions for constructing a triangle if the sum of the lengths of any two of its sides is greater than the length of the third side. But AB + BC = 15 cm, and AC = 15 cm, AC + CD = 25 cm, and AD = 25 cm.

Since the conditions are not met, this figure cannot be a trapezoid and a quadrangle.
