Call two regular polygons supplementary if the sum of an internal angle from each polygon adds up to

180^o

. For instance, two squares are supplementary because the sum of the internal angles is

90^o + 90^o = 180^o

. Find the other pair of supplementary polygons. Write your answer in the form

(m, n)

where m and n are the number of sides of the polygons and

m < n
