Exterior angles add up to 360 degrees
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.
There is such a thing as a regular heptagon, but it cannot be constructed under the rules of classical Greek construction. Any heptagon constructed under these rules will therefore be irregular. This is because the interior angle of a heptagon is (5pi)/7 radians, which cannot be constructed without a neusis construction or an angle trisector.
It is the regular 7 sided heptagon whose interior angles are greater than the regular 3 sided triangle
Each interior angle of a regular 7 sided heptagon is 128.'571428' degrees recurring decimal '571428'
If, by longer, you mean larger, the answer is a heptagon.
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.
900 degrees, and the heptagon does not need to be regular.

It is a 7 sided polygon known as an heptagon.
A regular heptagon doesn't have right angles, but an irregular heptagon can have 5 right angles.
It is the regular triangle whose exterior angles are greater than the regular heptagon
