The 8 interior angles add up to 1080 degrees
The addition of an extra side increases the total of the internal angles by 180° The sum of the internal angles of a polygon = (number of sides - 2) × 180°
...eight interior and exterior angles. ANGLES
octogon
The sum of the internal angles of a polygon of n sides is (n-2)*180 degrees.
A polygon with internal angles of 144 degrees is a dodecagon, which has 12 sides. In this case, each internal angle measures 144 degrees, and the sum of the internal angles for a dodecagon is 1,440 degrees (calculated as (12-2) × 180). This type of polygon can be regular if all sides and angles are equal.

An octagon is a polygon that has 8 sides and 8 interior angles
...eight interior and exterior angles. ANGLES
A polygon has an equal number of sides and angles. For example, a triangle has 3 sides and 3 internal angles.
octogon
The sum of the internal angles of a polygon of n sides is (n-2)*180 degrees.
8 angles and vertices
its an octogon. octo means eight

The polygon has eight (8) sides.
A polygon with eight sides and eight angles.
A polygon has exactly the same number of both internal and external angles to the number of sides. Assuming external angles count, there are two times the number of sides as the total number of angles
