Question 1019592
When you name a polygon, you name the vertices in order,
so in parallelogram MNPQ, vertex N is adjacent to vertices M and P,
and opposite vertex Q, which is also adjacent to M and P.
Angles MNP and PQM are opposite angles.
Angles NPQ and QMN are opposite angles.
You would se it better with a drawing:
{{{drawing(300,200,-1,5,-1,3,
line(0,0,3,0),line(1,2,4,2),
line(0,0,1,2),line(3,0,4,2),
locate(-0.1,0,M),locate(0.9,2.3,N),
locate(3,0,Q),locate(4,2.3,P)
)}}}
