find the sum of the measures of the interior angles of an octagon

To find the sum of the measures of the interior angles of an octagon, we need to use the formula for the sum of angles in a polygon.

The formula for the sum of the interior angles of an n-sided polygon is given by:

Sum of interior angles = (n - 2) * 180

In this case, we have an octagon, which is an 8-sided polygon. Therefore, we can substitute n = 8 into the formula:

Sum of interior angles = (8 - 2) * 180
= 6 * 180
= 1080

So, the sum of the measures of the interior angles of an octagon is 1080 degrees.
