The term "obtuse" refers to an angle greater than 90 degrees but less than 180 degrees, not the number of sides of a shape. Therefore, it doesn't have a specific number of sides associated with it. Shapes can have any number of sides and still contain obtuse angles. For example, a triangle can have one obtuse angle, while a quadrilateral can have multiple obtuse angles.
This depends on the polygon.For a triangle (3-sides) : maximum 1 obtuse angle.Quadrialteral (4-sides): maximum 3 obtuse angles.For polygons with more sides, it is possible for all angles to be obtuse.
All triangles have 3 sides.
zero
By definition, all triangles have 3 sides.
None normally but if it is in the shape of an isosceles triangle then it will have 2 equal sides.

None or two sides.

3 sides because every tiangle has 3 sides.
By definition, all triangles have 3 sides.
A pentagon: 5 sides.
none
None normally but if it is in the shape of an isosceles triangle then it will have 2 equal sides.
An obtuse triangle has 3 sides.
it has one obtuse angle and none of the sides are congrent
