Any obtuse triangle, any quadrilateral other than a square or rectangle, any regular polygon with 5 or more sides as well as most (but not all) irregular polygons of 5 or more sides.

-- 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 .
A trapezoid and a rhombus are examples of shapes with more than one obtuse angle.
An obtuse triangle has one of its angle greater that 90 degrees.His plate was in the shape of an obtuse triangle.
There are versions of quadrilaterals, pentagons and hexagons that have only two obtuse angles. If a shape with seven or more sides has two (or fewer) obtuse angles, it will also have at least one reflex angle and so will no longer be a convex polygon.

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.
An obtuse triangle has one of its angle greater that 90 degrees.His plate was in the shape of an obtuse triangle.
An obtuse triangle has 1 obtuse angle and 2 different acute angles and they all add up to 180 degrees
