A regular heptagon doesn't have right angles, but an irregular heptagon can have 5 right angles.
A heptagon has 900 degrees, which each angle measuring 900/7, or 128.5714286 degrees
The 7 exterior angles of a septagon or a heptagon add up to 360 degrees
Any angle that you like.
Each interior angle is approximately 128.57 * * * * * That is only true of a REGULAR heptagon. The question does not state that it is regular.
Ancient Greek "hepta" = seven, "gonia" = angle. It is a polygon with seven angles (vertices).

A heptagon. It can have a reflex interior angle, a triangle cannot.
heptagon
An octagon has 8 angles. A heptagon has seven. The difference is one angle.
Interior angle = 900/7 = 128.57 degrees, approx.
An interior angle of a heptagon can have ANY value between 0 and 360 degrees.
7 obtuse angle
The 7 exterior angles of a septagon or a heptagon add up to 360 degrees
Any angle that you like.
Seven, one stretching from each corner and making a right angle half way along the opposite side.
