A polygon with four or more sides can meet all of the requirements.

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.

Any polygon with 5 sides or more or a trapezoid that doesn't have a right angle in it or a kite that is not a square.

Yes, a rectangle can have one obtuse angle.

If one angle is a right angle, it is a right triangle. If one angle is an obtuse angle, it is an obtuse triangle. If there are no right nor obtuse angle then it is an acute triangle.

Yes. Any polygon with more than four sides MUST have at least one obtuse angle.

An obtuse triangle.

The answer to this would be any acute polygon, such as an equilateral triangle. The definition of acute polygons is that no angle in the polygon is greater than or equal to 90 degrees.

Not sure what the question means. A triangle or quadrilateral may but need not contain an obtuse angle. A pentagon or any polygon with more sides must contain at least one obtuse angle.

-- No right triangle, acute triangle, or equilateral triangle has an obtuse angle in it. -- If a triangle has an obtuse angle in it, then it's called an obtuse triangle. -- No triangle can have more than one obtuse angle in it .

Trapezoids ALWAYS have at least one obtuse angle (if they have two right angles, then there will only be one obtuse angle), usually two (in any other circumstance, they will have two obtuse and two acute angles).

-- If a triangle has an obtuse angle in it, then it's called an obtuse triangle. -- No triangle can have more than one obtuse angle in it . -- Right triangles, acute triangles, and equilateral triangles don't have any obtuse angles in them.

Yes, because the angles have to add up to 360º, at least one angle has to 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.
