Interior Angle of a Regular Octagon

Consider a regular octagon, which is a polygon with eight equal sides and equal angles. To calculate each interior angle of a regular octagon, you can use the formula for the measure of an interior angle:

$$ ext{Interior Angle} =\frac{(n - 2) imes 180^ ext{o}}{n} $$

where $n$ is the number of sides. For the octagon, $n = 8$.
