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.
it has one obtuse angle and none of the sides are congrent
