Since vertically opposite angles are equal, let's add another angle () to the diagram.

Since angles in a triangle add to 180°, we can write two equations:
w + x + y = 180
w + p + q = 180

Since both equations are equal to 180, we can write: w + x + y = w + p + q
Now subtract w from both sides of the equation to get: x + y = p + q

Cheers,
Brent
