if you are talking about regular polygons, then nothing has an obtuse angle. otherwise, pretty much any shape can have an 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 .
Yes, because the angles have to add up to 360º, at least one angle has to be obtuse.
A polygon with four or more sides can meet all of the requirements.
An obtuse triangle has 1 obtuse angle and 2 different acute angles and they all add up to 180 degrees
-- 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.
It needs at least 1 obtuse angle. Usually you can only have one obtuse angle, so the rest would be acute.
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).

91 degrees
No. A triangle can have only one obtuse angle. A triangle must have at least two acute angles
90 degrees
