Do you know the formula for finding the interior angles of a polygon?

ranga · Answer

A regular polygon has equal sides.  Each side will make equal angle at the center.  This polygon has 8 sides.  Together the 8 sides will make 360 degrees at the center.  How much will each angle be?  For example, angle AOB = ?

I really have noooo idea.. Its just my LAST question=]

anonymous · Answer

The formula is where n represents the number of sides of the polygon.. $$\frac{ (n-2)\times180 }{ n }$$

ranga · Answer

The question here does not ask for the interior or exterior angles of a polygon.

The angle made by each side at the center = $\Large \frac {360}{n}$.

Here, n = 8.  Angle AOB = $\Large \frac {360}{8} = ?$

You are correct..The cardinal sin of me not correctly reading the question.
