7 obtuse angle
A heptagon. It can have a reflex interior angle, a triangle cannot.
heptagon
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
no
An interior angle of a heptagon can have ANY value between 0 and 360 degrees.
The 7 exterior angles of a septagon or a heptagon add up to 360 degrees
Any angle that you like.
7
Each interior angle of a regular 7 sided heptagon is 128.'571428' degrees recurring decimal '571428'
the interior angle is about 128.571428 the exterior angle is about 51.4285
The triangle has a larger interior angle than the heptagon because the heptagon has more sides.
A regular heptagon doesn't have right angles, but an irregular heptagon can have 5 right angles.
