What is the supplementary angle of 1 degree? Here we will define the supplementary angle of 1 degree, show you how to calculate the supplementary angle of 1 degree, and even illustrate the supplementary angle of 1 degree (1°) so you have a solid understanding of what it means.
The supplementary angle of 1 degree, also known as the supplement angle of 1 degree, is the angle that when added to 1 results in a sum of 180. Therefore, to calculate the supplement angle of 1 degree, we subtract 1 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 1 = 179
179 degrees
1 degree plus the supplementary angle of 1 degree equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 1 degree colored in red and the supplementary angle of 1 degree, which is 179 degrees, colored in green.
As you can see from the illustration above, 1 degree and 179 degrees form a straight line together. This proves that the two angles, 1 degree and 179 degrees, are supplementary angles.
