Yes it must have at least one (really, it needs two or more). The sum of the interior angles in a pentagon is 540°.
If you had 4 angles @ 90°, then the fifth angle would need to be 180°, which is a straight line, then it would be a rectangle, not a pentagon, so you need at least two angles, greater than 90°.

What is the generalization for a obtuse triangle quadrilateral and pentagon?
Not sure what the question means. A triangle or quadrilateral may but need not contain an obtuse angle. A pentagon or any polygon with more sides must contain at least one obtuse angle.

WHAT shape has 2 right angle 2 obtuse angle 1 acute angle?
An irregular pentagon.An irregular pentagon.An irregular pentagon.An irregular pentagon.
How many obtuse angles does a pentagon have?
Hi A pentagon has 540 degrees and five sides. If it is a regular pentagon, then each angle is 108 degrees. An obtuse angle is greater than 90°. A pentagon can be constructed with 2 obtuse angles and 3 non-obtuse (either acute or right) angles. Example: if it had 3 angles of 90° = 270°. 540° - 270° = 270°, which would be split between 2 angles (each between 90° and 180°).
Which figure has 2 right angles 2 obtuse angles and 1 acute angle?
A pentagon.
What shape has 2 right angles 2 obtuse angles and 1 acute angle?
Because it has five angles it is a irregular pentagon.
