Define complementary in math. Therefore the two smaller ones must add to 90 and so are complementary by definition. 5 and 85 are complementary angles. Complementary angles are two angles whose measures have a sum of 90. One angle is 90 and all three add up to 180.
In general two things are complementary when they add up to a whole of some kind. They don t have to be next to each other just so long as the total is 90 degrees. Complementary angles can be adjacent or non adjacent. For example in geometry two angles are said to be complementary when they add up to 90.
In a right triangle the two smaller angles are always complementary. One angle is said to be the complement of the other. See the page on right triangles and convince yourself that this is true. Each angle is the complement of the other.
60 and 30 are complementary angles. Two angles are complementary when they add up to 90 degrees a right angle. Two angles are said to be complementary angles if they add up to 90 degrees. Angle 1 and angle 2 are complementary if angle 1 angle 2 90 circ.
