None, because there is no such shape.
There is a heptagon (7 sides) or an octagon (8 sides), and the answers will be different depending on what you meant.
In their convex form, either can have at most 3 right angles. But a concave heptagon can have any number up to 6 right angles. A concave octagon can have up to 7 interior right angles. It can, in fact have all eight if reflex right angles (270 deg) are allowed.

A hectagon (or hectogon) is a Polygon with 100 angles.A heptagon has 7, and a hexagon has 6.
Rectangle, octagon, hectagon, square...

i dont know, find a hectagon and count the sides trololo
A hectagon has 100 sides. It might be confused with a heptagon which has 7 sides.
4 right angles, no other angles.

It has 6 angles, none of which are right angles.
It is not possible to answer the question since there is no such shape. Please check your spelling and resubmit.
