what is the measurement of each interior angle of a heptagon

A regular heptagon, in which all sides and all angles are equal, has internal angles of 5π/7 radians (128​ 4⁄7 degrees). Its Schläfli symbol is {7}.

To find the measurement of each interior angle of a heptagon, we can use a formula:

The formula for finding the measurement of each interior angle of a polygon is:
Interior angle = (n-2) * 180 / n

In this formula, "n" represents the number of sides of the polygon. In the case of a heptagon, "n" is equal to 7.

So, for a heptagon, the formula becomes:
Interior angle = (7-2) * 180 / 7

Now, let's do the calculation:
Interior angle = 5 * 180 / 7

The interior angle of a heptagon is approximately 128.57 degrees.
