A heptagon is a seven-sided polygon. It has seven interior angles. If it is a Regular polygon, each interior angle measures approximately 128.57 degrees, to a total of 900 degrees.
Sum of interior angles of a polygon of n sides is (2n - 4) right angles. In our case the sum would be (14 - 4) x 90 degrees = 900 degrees. Hence each interior angle would be 900/7 = 128.57 degrees approximately.
900 degrees
It's 900 degrees, and it doesn't matter whether the 7-sided polygon is regular or not.
Interior angles total ((2 x 7) - 4) right angles which is 900 degrees. Exterior angles total 360 degrees. This is true of all convex polygons.
