polygon
I only know it's not a polygon
There is no polygonal shape which has exactly those angles. It is possible for a concave polygon with 6 or more vertices to have the given angles.
"z" has two acute angles a triangle can have 3 acute angles but also will have a angle >= 60degrees acute (also note for every acute angle a obtuse angle is formed the sum of the obtuse and acute angle will = 360) because of this a arrow is the only shape with two acute angles and 1 obtuse
2 obtuse and 2 acute in the classic kite shape.
a trapezoid :) * * * * * Not necessarily. A trapezoid can have two right angles, one acute and one obtuse angle. A parallelogram which is not a rectangle must have 2 acute and 2 obtuse angles.
A regular polygon of n sides (where n > 4) has n obtuse angles. Since there is no limit to the number of sides that a polygon can have, there can be no limit to the number of obtuse angles in a shape.
The only polygon with just acute angles is an acute angled triangle.

An obtuse triangle or an isosceles triangle if the 2 acute angles are equal in size
