What is the measure of each interior angle of a regular heptagon?

Use the formula for each interior angle of a polygon: A%5Bi%5D+=+%28%28n+-+2%29180%29%2Fn, where A%5Bi%5D is the measure of each interior angle, and n is the number of sides of the polygon. In this case, n = 7, since the polygon is a heptagon.

A%5Bi%5D+=+%28%28n+-+2%29180%29%2Fn ------ A%5Bi%5D+=+%28%287+-+2%29180%29%2F7 = 128.5714286 ≈ highlight_green%28128.57%5Eo%29
