It is a parallelogram.
trapezoid
Parallelogram.
Yes. Any polygon with more than four sides MUST have at least one obtuse angle.
square
No shape does. If it has 4 sides and one pair of parallel lines it cannot have only 1 right angle, it must either have: 1) 2 right angles, 1 acute acute and 1 obtuse angle; or 2) no right angles, 2 acute angles and 2 obtuse angles; in which case it would be a trapezium (trapezoid).
A rhombus - or parallelogram.

A polygon with two acute angles, two obtuse angles, and two pairs of parallel sides is known as a trapezoid (or trapezium in some regions). Specifically, it can be classified as an irregular trapezoid, where one pair of opposite sides is parallel, and the angles vary in measure. This configuration allows for the presence of both acute and obtuse angles while maintaining the parallel sides characteristic of trapezoids.
I only know it's not a polygon
The number of obtuse angles in a polygon can vary widely depending on the specific type of polygon. In general, a polygon can have zero, one, or multiple obtuse angles, but the total number of obtuse angles cannot exceed half of the polygon's total angles. For example, a triangle can have at most one obtuse angle, while a quadrilateral can have up to two. Ultimately, the distribution of obtuse angles depends on the polygon's shape and the measures of its angles.
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.
Obtuse angles.
The number of inside obtuse angles in a polygon can vary depending on the specific type and shape of the polygon. However, a polygon can have multiple obtuse angles as long as the sum of the interior angles remains consistent with the formula ( (n - 2) \times 180^\circ ), where ( n ) is the number of sides. For example, a polygon could have 2, 3, or more obtuse angles, as long as the total angle measure is maintained. Thus, there is no fixed number of obtuse angles for all polygons.
