A shape with five sides, one right angle, and one obtuse angle is known as a pentagon. Specifically, it can be an irregular pentagon, where the right angle is 90 degrees and the obtuse angle is greater than 90 degrees but less than 180 degrees. The remaining angles can be acute or right angles, as long as the total sum of the interior angles equals 540 degrees.
A rhombus.
It could be a trapezoid having 2 right angles, an obtuse angle and an acute angle
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.
A trapezoid can have 2 right angles, 1 acute angle and 1 obtuse angle that all add up to 360 degrees and it has a pair of parallel sides.
Irregular Rhombus
no
A rhombus.
a scalene triangle, an obtuse triangle, a right angle.
Types of triangle ; EQUILATERAL all three sides the same length and all three angles are 60 degrees. ISOSCELES Two sides the same length and two angles have the same degrees value. RIGHT-ANGLED All three sides can be of different lengths. However, it MUST have one Right-Angle (90 degrees) SCALENE All three sides of different lengths and all three angles of different angular values. NB In ALL four cases the sum of the interior angles MUST ADD TO 180 DEGREES.

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.
A trapezoid can have 2 right angles, 1 acute angle and 1 obtuse angle that all add up to 360 degrees and it has a pair of parallel sides.
Irregular Rhombus
a parelelogram
If it has an obtuse angle
No but a right angle triangle has perpendicular sides and an hypotenuse.
