Most do, but a square or rectangle is a special case and has all right angles.

Do all parallelograms have at least one right angle?
The simple answer is no, not all parallelograms have at least one right angle. However, there are some that do. Rectangles and squares are 'special' parallelograms that all have at least one right angle.
What polygon has at least one obtuse angle?
An obtuse triangle has 1 obtuse angle and 2 different acute angles and they all add up to 180 degrees
Which shapes have an obtuse angle?
Obtuse triangles have an obtuse angle, and regular shapes with a number of sides equal to or greater than five have angles that are all obtuse.
Can an obtuse triangle have more than one obtuse angle?
No, an obtuse triangle can not have more than one obtuse angle. This is because all of the angles have to add up to 180 and the smallest obtuse angle you can have is 91 degrees. So 180-91=89. 89 degrees is the angle that you need to complete the triangle and it is an acute angle. Therefore, you can not have more than one obtuse angle in an obtuse triangle.
How many obtuse angles are there in a obtuse triangle?
There is one obtuse angle, and the other two are acute angle because in all the whole triangle is 180 degrees.

Can A parallelogram can have obtuse angles?
Yes. All rhombuses (rhombi), apart from the special case of squares, are parallelograms with 2 obtuse angles.
What are all of the obtuse angles?
Any angle that is above 90 degrees is considered an obtuse angle.
Which shapes have an obtuse angle?
Obtuse triangles have an obtuse angle, and regular shapes with a number of sides equal to or greater than five have angles that are all obtuse.
Is it possible for a quadrilateral to have 2 obtuse angels?
Yes. All parallelograms, except their degenerates form (rectangles), must have two obtuse angles.
What is the measurement of every obtuse angle?
It depends on the angle not all obtuse angles measure the same. To measure an angle you use a protractor.
Is the angles on a hexagon acute right angle or obtuse?
An angle in a hexagon can have any value at all. It can be acute, a right angle, an obtuse angle or even a reflex angle.
Is a straight angle less then an obtuse angle?
no it is more. obtuse is 91 - 179 and straight angles are all 180
Can an obtuse triangle have more than one obtuse angle?
No, an obtuse triangle can not have more than one obtuse angle. This is because all of the angles have to add up to 180 and the smallest obtuse angle you can have is 91 degrees. So 180-91=89. 89 degrees is the angle that you need to complete the triangle and it is an acute angle. Therefore, you can not have more than one obtuse angle in an obtuse triangle.
Can a triangle have all obtuse angles?
No. A triangle can have a maximum of one obtuse angle.
