Answer

On placing two identical set squares with angles $30^{\circ}-60^{\circ}-90^{\circ}$ adjacently, we get a parallelogram as shown in the figure.
Then, this figure helps us to confirm the property that opposite angles of a parallelogram are of equal measures.
[in this figure, each angle is equal to $90^{\circ}$]
