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.
A regular polygon has equal angles AND sides.
Any number of sides of 5 and above because all interior angles of regular polygons in this category will have obtuse interior angles.
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 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.
Not only can a regular polygon have equal angles and sides, it must have them.
