Question

two angles whose sum is 180 degree are called​

Answer 1

Answer:

two angles which add up to 180 are called linear pair or supplementary angles

Answer 2

Answer: If two angles sum up to 180° , they are termed  as supplementary angles.

Step-by-step explanation:

• When combined, supplementary angles make a straight angle (180 degrees). In other words, if angle 1 plus angle 2 equals 180 degrees, angle 1 and angle 2 are supplementary. In this instance, Angles 1 and 2 are referred to as "supplements" of one another.
• If two angles for example where sum is 130° + 50° = 180°. Then, these two angles fit the concept of supplementary angles.
  It is possible for supplementary angles to be either nearby or not. There are hence two categories of additional angles. Below is an explanation of each of these extra angles.
  1. Adjacent supplementary angles

        2. Non-adjacent supplementary angles

• When two angles add up to 180 degrees, we refer to them as supplements of one another. Since each supplementary angle is stated to be a "supplement" to the other, we know that the sum of two supplementary angles is 180 degrees. Therefore, the angle's supplement is calculated by deducting it from 180 degrees. This indicates that (180 - x)° is the supplement of x°.
• For instance, the addition of 77° is calculated by deducting 180° from it. Therefore, its addition is (180-77)° = 103.
