If angle A plus angle B equals 90 degrees then A and B are what kind of angles?
Complementary.
Can a quadrilateral abcd be aparallelogram if angle d plus angle b equals 180?
Yes, a quadrilateral ABCD can be a parallelogram if angle D plus angle B equals 180 degrees. In a parallelogram, opposite angles are equal, and consecutive angles are supplementary (their sum equals 180 degrees). Therefore, if angle D and angle B are supplementary, it is consistent with the properties of a parallelogram. Thus, the condition does not contradict the definition of a parallelogram.
Prove that the sum of the measures of the three angles of every triangle is 180 degrees?
Angle a plus angle b subtract from 180 equals angle c
What is the definition of angle addition postulate?
The angle addition postulate states that if a point lies inside an angle, the sum of the two smaller angles formed is equal to the measure of the larger angle. In other words, if point B is located within angle AOC, then the measure of angle AOB plus the measure of angle BOC equals the measure of angle AOC. This postulate is fundamental in geometry for solving problems related to angles.
Given a paralleogram ABCD angle A equals 30 plus 5x and angle D equals 15 plus 10x What is x?
9 degrees
If angle A plus angle B equals 90 degrees then A and B are what kind of angles?
Complementary.
If in angle A plus measure angle B equals 180 then angle A and angle B are?
The angles are supplementary if they have a sum of 180 degrees.
If in angle A plus the measure of angle B equals 180 then angle A and angle B are what angles?
I am pretty sure they would be considered supplimentry angles. m<1+m<2=180 : definition of supplimentry

Two angles are supplementary the first angle measure 60 degrees what is the measurement of the second angle?
120 Since the measures of the angles of supplementary angles add up to 180, 60 plus something else equals 180. 180-60=120
If angle A plus angle D equal 90 then A and D are what type of angles?
Acute

9 degrees
Angles X and Y are supplementary If the measure of angle X equals 2x plus 4 and the measure of angle Y equals 4x plus 20 then what is the measure of each angle and why?
X = 180 - Y so 180 - Y = 2x + 4 and Y = 4x + 20 so 180 - 4x - 20 = 2x + 4 therefore 6x = 156 so x = 26 making Angle X = 56o and Angle Y = 124o
What quadrilateral has two right angles only one set of parallel sides and no lines of symmetry?
It is a trapezoid that can have two right angles plus one obtuse angle plus one acute angle and the four angles add up to 360 degrees.
