they add up to 180 so it depends. you have to know one of the measures
If angles A and B are supplementary, their measures add up to 180 degrees. Let angle B be ( x ). Then angle A, being twice as large, is ( 2x ). Setting up the equation, we have ( x + 2x = 180 ), which simplifies to ( 3x = 180 ). Solving for ( x ), we find ( x = 60 ) degrees for angle B, and angle A measures ( 120 ) degrees. Thus, angle A is 120 degrees and angle B is 60 degrees.
An angle which has measure between 90 degrees and 180 degrees is an obtuse angle.
Let two adjacent angles be ( \angle A ) and ( \angle B ) such that ( \angle A + \angle B = 180^\circ ). The angle bisector of ( \angle A ) divides it into two equal angles, ( \frac{1}{2} \angle A ), and the angle bisector of ( \angle B ) divides it into ( \frac{1}{2} \angle B ). Therefore, the angle formed by the two bisectors is ( \frac{1}{2} \angle A + \frac{1}{2} \angle B = \frac{1}{2} ( \angle A + \angle B ) = \frac{1}{2} \times 180^\circ = 90^\circ ). This proves that the bisectors of two adjacent supplementary angles indeed form a right angle.

supplementary angles
Draw angle C and bisect it into A & B.

The transitive property is if angle A is congruent to angle B and angle B is congruent to angle C, then angle A is congruent to angle C.
The angles are supplementary if they have a sum of 180 degrees.

for a+ NEVERIn a parallelogram opposite angles are equal. Thus angle c = angle a = 40o.The sum of all the angles in a quadrilateral is 360o, so:angle a + angle b + angle c + angle d = 360o=> 40o + angle b + 40o + angle d = 360o=> angle b + angle d = 280o.
right angle
Angle b is acute angle, if any angle less than 90 degrees then it is called acute angle if more than 90 degrees then it is obtuse angle if it is equal to 90 degrees then it is right angled
angle B and angle D are supplements, angle B is congruent to angle D, angle A is congruent to angle A, or angle A is congruent to angle C
An angle which has measure between 90 degrees and 180 degrees is an obtuse angle.
