180 degrees
Angles on a straight line always add up to 180 degrees. This is because a straight line represents a half-turn, and the total measure of angles around a point is 360 degrees. Therefore, the angles on one side of the straight line must sum to half of that total, equating to 180 degrees.
If the two angles sum adds up to 180 degrees, then they are supplementary angles.
The sum of the measures of the angles on a line is always 180 degrees. This is because a straight angle, which is formed by a line, measures 180 degrees. Therefore, any two angles that form a linear pair (i.e., they are adjacent and their non-common sides form a straight line) will add up to 180 degrees.
a straight line or supplementary angles...which equal to 180 degrees.
Angles that equal 180 degrees are known as straight angles. When two angles sum up to 180 degrees, they are referred to as supplementary angles. A straight angle is formed when two rays point in opposite directions, creating a straight line. In geometry, straight angles play a significant role in various theorems and properties.
Draw any straight line through the point. The sum of the angles at the point are the sums of the angles on each side of the line - which are known to be 180o. Thus: the sum of the angles at the point = the sum of the angles of each side of the line = 180o + 180o = 360o The sum of the a
180 degrees.
Because that is what a straight line (or straight angle) is.
Sum of adjacent angles on a straight line.
Angles on a straight line always add up to 180 degrees. This is because a straight line represents a half-turn, and the total measure of angles around a point is 360 degrees. Therefore, the angles on one side of the straight line must sum to half of that total, equating to 180 degrees.

The sum of the three constitutive angles of a planar triangle is always equal to 180 degrees or two right angles. And there are two things in it as well. they are diagonal and a exterior angle

The sum is two straight angles or 360 degrees.
