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