900 degrees, and the heptagon does not need to be regular.
The sum of the measures of the interior angles of a heptagon is 900 degrees.
900
900 degrees.Explanation: The sum of the measures of the interior angles of a heptagon is 900°. A heptagon has 7 sides. So to calculate the sum of the measures of the interior angles in a heptagon, substitute 7 for n in (n − 2) • 180°. You get (7 − 2) • 180°, or 5 • 180°= 900°.
The 7 interior angles of a heptagon add up to 900 degrees
The 7 interior angles of a heptagon add up to 900 degrees
The 7 interior angles of a heptagon add up to 900 degrees
The angles in a 7 sided heptagon add up to 900 degrees
A heptagon has 7 sides and 7 angles. The sum of the interior angles is 900°. If the heptagon is a regular heptagon, meaning all sides and angles are congruent, then the formula (180(n-2))/ n gives the individual interior angle measure. "n" is the number of sides in this case. In a regular heptagon, the interior angle measures 128 4/7 degrees.
(7-2)*180 = 900 degrees
Exterior angles 360 degrees Interior angles 900 degrees
Each interior angle of a regular heptagon measures 900/7 degrees.The interior angles of all polygons meeting at a point must sum to 360 degrees. But that would require 360 / (900/7) = 2.8 - that is you would require 2.8 regular heptagons to meet at each vertex. Since it is not possible to have a fraction of a heptagon. the tessellation required by the question is impossible.
