The 7 interior angles add up to 900 degrees
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.
Each interior angle measures 128.57 degrees rounded
51º per interior angle
In each interior angle: 128o 34' 17.14''
(n-2)*180 = 900 degrees
A polygon with seven sides is called a heptagon. A heptagon has seven interior angles totaling 9000 and seven exterior angles totaling 3600
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.
The heptagon (7 sided polygon) cannot tessellate. The exterior angle of the heptagon is 51.43 degrees which makes the interior angle 128.57 degrees.
It is a heptagon that is a polygon having 7 sides with 7 interior angles.
The interior angles of a 7 sided polygon add up to 900 degrees
