Question

The Polygon Angle-Sum Theorem states the following: The sum of the measures of the angles of an n-gon is ____. (1 point)

(n – 1)180o

(n – 2)180o

Answer 1

its the 2nd one.

to check, a triangle has 3 sides and angle sum of 180

so ( 3 - 2)*180 = 180

so it seems to work.

Answer 2

thank you so much
