An obtuse triangle has 3 sides.
A pentagon: 5 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.
Millions of sides. However, I think you mean 'MINIMUM' number of sides for regular polygons with OBTUSE interior Angles.. The answer is '5' ( pentagon.
An obtuse triangle can have at most one obtuse angle.A quadrilateral can have up to 3.Every regular polygon (shapes with equal sides and angles) with more sides than a square has obtuse angles.PentagonHexagonHeptagonOctagonNonagonDecagon
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 regular polygon has equal angles AND sides.
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.
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).
