1. A pair of non-adjacent supplementary angles.

It's urgent...having exam tomorrow

We know : Two angles which do not have common ray coming out of the vertex going between two other rays are called as a non adjacent angles. If the sum of two non adjacent angles is 180$\xb0$ then those angles are called as non adjacent supplementary angles .

We draw non adjacent supplementary angles , As :

Here :

$\angle $ ABC + $\angle $ PQR = 180$\xb0$

So,

$\angle $ ABC and $\angle $ PQR are non adjacent supplementary angles .
