If they are both regular then the 7 sided heptagon has a larger interior angle than a 3 sided equilateral triangle.
The triangle has a larger interior angle than the heptagon because the heptagon has more sides.
Either could have a larger interior angle. If they were regular, then the interior angle of a triangle would be 60 degrees whereas that of a heptagon would be 128.57 degrees. The REGULAR heptagon would have a larger interior angle than a REGULAR triangle.
heptagon
A heptagon. It can have a reflex interior angle, a triangle cannot.
If, by longer, you mean larger, the answer is a heptagon.
Interior Angles of a Triangle: 60 Exterior Angles of a Triangle: 120 Interior Angles of a Heptagon 128 (approx) Exterior Angles of A Heptagon 52 (approx) Answer: Triangle
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.
It is the regular 7 sided heptagon whose interior angles are greater than the regular 3 sided triangle
That depends on the type of triangle it is but if it's an equilateral triangle then its exterior angle is greater than that of a regular heptagon
It is the equilateral triangle that has the largest exterior angle of 120 degrees
An interior angle of a heptagon can have ANY value between 0 and 360 degrees.
the interior angle is about 128.571428 the exterior angle is about 51.4285
