the letter C lies on top, the first point of the angle. A is the "vertex" it connects both lines to form an angle the bottom could be letter B. "<" that's an angle. B and C could never be on the Vertex.
they add up to 180 so it depends. you have to know one of the measures
An angle which has measure between 90 degrees and 180 degrees is an obtuse angle.
The VERTEX of the angle is always in the middle... so if it is angle ABC, then you can also name it CBA as long as the vertex letter is in the middle, usually there are only 2 ways to name an angle.Also, if there aren't any other angles with the same vertex, you can just call angle ABC, angle B.Summary: If you have an angle:the vertex is labeled B, the others are A and C. what can you call the angle?Answer: ABC,CBA or B
Complementary.

Yes, so as long as the angle being identified (in this case, angle b) is in the center.
supplementary angles
Any letter can be used for any angle. It is conventional, though, to go in one direction around any polygon.
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.
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
