An exterior angle is 360/7 = 51.4286 degrees.
So interior angle is 180 - exterior angle = 128.57 degrees (approx).
A heptagon has 7 sides. sum_of_interior_angles = (number_of_sides - 2) x 180o ⇒ sum_of_angles_for_heptagon = 5 x 180o = 900o ⇒ interior_angle_of_regular_heptagon = 900o ÷ 7 = 1284/7o ~= 128.6o.
It is the regular heptagon which has the larger interior angle. The rule is that as the number of sides of a regular polygon increases then the external angle decreases while the interior angle increases The summation of the interior and external angleof one vertex is 180 degrees.

Answer: 128.57 degrees The measure of one angle in a REGULAR polygon can be found with the formula: ((n-2)x 180degrees)/n --> (7-2)x 180= 900degrees--> 900degrees/7= approx. 128.57 degrees. The polygon MUST be regular (i.e. all sides the same length and all angles the same measure
In a regular heptagon, each interior angle is 180o - 360o ÷ 7 = 1284/7o ≈ 128.57o;in a non-regular heptagon, one of the interior angles ("an interior angle") could be any value greater than 0o and less than 360o except 180o.
900/7 = 128.57 deg approx.

An interior angle of a heptagon can have ANY value between 0 and 360 degrees.
