What is the supplementary angle of 80 degrees? Here we will define the supplementary angle of 80 degrees, show you how to calculate the supplementary angle of 80 degrees, and even illustrate the supplementary angle of 80 degrees (80°) so you have a solid understanding of what it means.
The supplementary angle of 80 degrees, also known as the supplement angle of 80 degrees, is the angle that when added to 80 results in a sum of 180. Therefore, to calculate the supplement angle of 80 degrees, we subtract 80 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 80 = 100
100 degrees
80 degrees plus the supplementary angle of 80 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 80 degrees colored in red and the supplementary angle of 80 degrees, which is 100 degrees, colored in green.
As you can see from the illustration above, 80 degrees and 100 degrees form a straight line together. This proves that the two angles, 80 degrees and 100 degrees, are supplementary angles.
