What is the supplementary angle of 171 degrees? Here we will define the supplementary angle of 171 degrees, show you how to calculate the supplementary angle of 171 degrees, and even illustrate the supplementary angle of 171 degrees (171°) so you have a solid understanding of what it means.
The supplementary angle of 171 degrees, also known as the supplement angle of 171 degrees, is the angle that when added to 171 results in a sum of 180. Therefore, to calculate the supplement angle of 171 degrees, we subtract 171 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 171 = 9
9 degrees
171 degrees plus the supplementary angle of 171 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 171 degrees colored in red and the supplementary angle of 171 degrees, which is 9 degrees, colored in green.
As you can see from the illustration above, 171 degrees and 9 degrees form a straight line together. This proves that the two angles, 171 degrees and 9 degrees, are supplementary angles.
