They are called supplementary angles
Supplementary angles.
Supplementary angles are two angles that, when added together, are equal to 180 degrees.
The triangle has three exterior angles. Added together, their total is 180 degrees.(Same as the total of the three interior angles when they're added together.)
180 degrees
Yes, it is possible for two angles not to add together to 180 degrees.

180 degrees
Yes, it is possible for two angles not to add together to 180 degrees.
Two angles put together to create a 180 degree angle.Supplementary angles add up to 180 degrees as for example the supplementary angle of 120 degrees is 60 degrees because 120+60 = 180 degrees.
One right angle is equal to 90 degrees, or a vertical line extending from the o degree plane. Therefore, two right angles, presumably side to side, would have 180 degrees, since together the would be supplementary angles. Supplementary angles are two angles which combine to from 180 degrees, and 90 plus 90 would equal 180 degrees. Look at angle DBE and at angle EBC. Each are 90 degree angles, or right angles, and together equal 180 degrees.
Supplementary angles add up to 180 degrees whereas complementary angles add up to 90 degrees
3. They must added together equal 180 degrees.
The sum of the interior angles of a triangle is 180 degrees. This is because one angle of a triangle is 60 degrees.
Supplementary angles add up to 180 degrees
In a triangle, the sum of the measures of the angles is 180 degrees.
