With no acute or obtuse angles, the shape must only have right angles. For a quadrilateral, that limits it to a square or rectangle. Because each side has a different length than the one next to it, it has to be a rectangle.
(Or, it could be a shape with any amount of sides above 4, as long as the angles are all right angles)
A pentagon maybe even A polygon

quadrilateral means having all sides the same length. when you make a shape with 3 obtuse angles and with the same length on the sides, only 3 of them will have the same length which is the sides of the 3 obtuse angles. then the last side will be too long. obviously it is no more quadrilateral.
An obtuse triangle has 1 obtuse angle and 2 different acute angles whereas the 3 angles add up to 180 degrees.
rhombus
I only know it's not a polygon
A pentagon maybe even A polygon
Rhombus ; Internal 2 acute and two obtuse angles; four sides of equal length, opposite sides are parallel. Rectangle ; Internal angles are all 90 degrees(right angles), opposite sides of equal length and parallel. Adjacent sides are of different length.

rhombus
The word 'Triangle' is a collective noun for different shaped triangles. They are ;- Equilateral(Acute) ; all sides are the same length , and all angles are 60 degrees. Isosceles (Can be Obtuse) ; two sides are the same length and two angles are equal. Right-angles (only Acute) ; one of the angles is a right angle(90 degrees) Scalene ; All sides are different length and all angles are different values. May be either acute of obtuse. For ALL triangles, on a plane surface, the sum of the interior angles is ALWAYS 180 degrees. NB For triangles drawn on a 3-dimensional surface, ( a sphere ; the Earth) the angles may add to 360 degrees.
a rhombus
A rhombus.
An OBTUSE Triangle. Names for other types of triangle. Equilateral [ all angles 60 degrees and all sides the me length). Isosceles ; Two angles are equa; and two sides the same length Obtuse ; one angle between 9 degrees and 180 degrees. Right-Angles ; One right angle. Scalene ; three angles unequal and three sides unequal length.
No there are different angle such as right angles, obtuse angles, and acute angles.
