great question!
n.....angle sum
3.....180
4.....360
5.....540
6.....720
see if you can find a pattern/relation between n and the angle sum
This is the question Im having trouble with
Assume that the angle sum in a triangle is invariant. Use that fact to write an argument that for n-sided polygons, the angle sum is also invariant. Find a rule that will tell you the sum if you know the number of sides.
Can anyone help?
