As the number of sides increases by 1, the angle sum increases by 180 degrees.

As the number of sides increases, each individual angle measure increases.

Yes, the pattern still applies Yes, the pattern still applies! The “LENGTH” of sides does NOT have any bearing on the size of the angle.

S = 180 (n - 2) or S = 180n - 360

A = 180 (n – 2) n A = 180n – 360 n or A = 180 - 360 n or
