Depends on a concave what. There can be infinitely many right angles in concave shape that keeps going in and out before returning to its starting point.

How many right angles does a hectagon have?
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.
How many different types of pentagons are there?
It depends on how they are classified. They can have 1 to 4 acute angles, they can have 1 to 4 right angles, they can have 1 to 5 obtuse angles. The individual values of the angles will generate different pentagons. They can be regular or irregular. They can be convex or concave.
Is an acute angle a concave or convex angle?
All angles < 180 degrees are concave. An acute angle is < 90 degrees. So, all acute angles are concave.
How many angles and how many right angles in a square?
4 right angles, no other angles.
What shape has 3 right angles and 1 obtuse angle and 1 acute angle?
There is no polygonal shape which has exactly those angles. It is possible for a concave polygon with 6 or more vertices to have the given angles.
How many right angles does a rectangular pentagon have?
It could have four if it is concave.
How many right angles does a hectagon have?
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.
What is the greatest number of right angles a hexagon can have?
A concave irregular hexagon can have up to 6 right angles. A convex irregular hexagon can have up to 3 right angles.
What shape has 10 right angles?
An irregular (concave) polygon with 10 or more sides.
How many different types of pentagons are there?
It depends on how they are classified. They can have 1 to 4 acute angles, they can have 1 to 4 right angles, they can have 1 to 5 obtuse angles. The individual values of the angles will generate different pentagons. They can be regular or irregular. They can be convex or concave.
Are concave angles parallel?
Angles cannot be parallel.
How many acute angles are in a hexagon?
None. Though there can be ten if the hexagons are concave hexagons.
You have four right angles but you are not just a rectangle What are you?
A square. Or an irregular, concave shape with with 5 or more sides.
What is a7 sided shape with 4 right angles?
It is an irregular, concave heptagon. But the shape has no special name.
Is an acute angle a concave or convex angle?
All angles < 180 degrees are concave. An acute angle is < 90 degrees. So, all acute angles are concave.
How many angles and how many right angles in a square?
4 right angles, no other angles.
What is a 7 sided shape called with 4 right angles?
This would be a type of concave or reentrant polygon, but might also have a specific name, perhaps a concave heptagon, or a reentrant heptagon.
