An obtuse triangle has 3 sides.

A regular polygon of n sides (where n > 4) has n obtuse angles. Since there is no limit to the number of sides that a polygon can have, there can be no limit to the number of obtuse angles in a shape.

The internal angles of a regular nonagon (a polygon having 9 sides) are obtuse angles of 140o.

Obtuse angles.

An obtuse angle is an angle that is greater than 90 degrees but less than 180 degrees. The internal angles of any regular polygon with 5 or more sides will be obtuse.

A hexagon has six angles. A regular hexagon has six angles and each one is equal in measure to 120 degrees. 120 degrees is an obtuse angle. Any regular polygon with at least 6 sides has at least 6 obtuse angles.

Yes the interior angles of a regular octagon are obtuse.

A regular hexagon has all angles obtuse.

There are 3 obtuse angles in a heptagon.

Any number of sides of 5 and above because all interior angles of regular polygons in this category will have obtuse interior angles.

Parallelogram.

A regular octagon has 8 interior obtuse angles.

Yes a regular pentagon has 5 obtuse angles of 108 degrees

A regular pentagon consists of 5 angles of 108° which are obtuse angles.

octagon, trapezoid, pentagon...* * * * *Not true.A trapezium (or trapeziod) must have at least one acute angle.Any regular polygon with 5 or more sides has all obtuse angles. However, an irregular polygon can always have one or more non-obtuse angles (acute, right or even reflex).

All obtuse angles is impossible- the sides wouldn't connect. If it has one (the most it could have), it is classified as obtuse _______ (name of polygon ex. triangle, hexagon, etc)

If it is a 'regular' hexagon, then all angles are congruent, and all are obtuse.

There are 6 obtuse angles in a regular hexagon that add up to 720 degrees.

It could be any irregular polygon with 4 or more sides (and 4 or more angles).

In a regular hexagon there are 6 obtuse interior angles.
