What is the complementary angle of 80 degrees? Here we will define the complementary angle of 80 degrees, show you how to calculate the complementary angle of 80 degrees, and even illustrate the complementary angle of 80 degrees (80°) so you have a solid understanding of what it means.
The complementary angle of 80 degrees, also known as the complement angle of 80 degrees, is the angle that when added to 80 results in a sum of 90. Therefore, to calculate the complement angle of 80 degrees, we subtract 80 from 90. Here is the formula, the math, and the answer:
90 - angle = complement angle
90 - 80 = 10
10 degrees
80 degrees plus the complementary angle of 10 degrees equals 90 degrees, which means that together they will make an L-shaped 90-degree angle.
The illustration below shows 80 degrees colored in red and the complementary angle of 80 degrees, which is 10 degrees, colored in green.
As you can see from the illustration above, 80 degrees and 10 degrees form an L-shaped angle together. This proves that the two angles, 80 degrees and 10 degrees, are complementary angles.
