What is the measure of an interior angle of a regular hexagon?

CORRECT

The measure of an internal angle of an regular polygon can be determined using the following equation, where equals the number of sides:

$\angle =\frac{180(n-2)}{n}$

$\angle=\frac{180(6-2)}{6}=\frac{180(4)}{6}=120$

190

CORRECT

180

170

200

210

If a triangle has 180 degrees, what is the sum of the interior angles of a regular octagon?

CORRECT

The sum of the interior angles of a polygon is given by where = number of sides of the polygon. An octagon has 8 sides, so the formula becomes
