If it is a 'regular' hexagon, then all angles are congruent, and all are obtuse.
acute
yes
A scalene triangle
It is a rhombus
Parallelograms normally have 2 congruent obtuse angles and 2 congruent acute angles that altogether add up to 360 degrees
An obtuse triangle must have two acute angles and these can be congruent.
In general a rhombus has one opposite pair of congruent acute angles and one opposite pair of congruent obtuse angles. A square, however, is a rhombus with four right angles.

No.
No, there are different kinds of angles, such as acute, reflex, straight and obtuse. A right angle is 90°.
By Definition, a triangle with two Congruent Sides is an Isosceles Triangle. For ALL angles to be Acute, that is, LESS than 90o , the two opposite angles must be greater than 45o. Remember that the SUM of the angles in a Triangle must equal 180o.
