Want this question answered?
Trigonometric functions, exponential functions are two common examples.
ANY two angles that total 90o, eg the "other" angles in a right-angled triangle.
That is exactly it, complementary means two angles that add up to 90 degrees. 25 is the complementary of 65, and vise versa.
Inverse functions are two functions that "undo" each other. Formally stated, f(x) and g(x) are inverses if f(g(x)) = x. Multiplication and division are examples of two functions that are inverses of each other.
The axis of symmetry. Which is a line that you can reflect two functions of off the axis of symmetry.
Ice structure and Diamond structure.(two more examples of a non-silicate structure: Pyrite structure and natural gas hydrates).
it is a support structure

The exoskeleton both protects the organs and gives the body structure.
No only two angles can be complementary
dna is a double stranded structure consisting of two complementary strands which are held together by hydrogen bonding between the base pairs of the two strands
A complementary angle is two angles whose sum is 900 (degrees). So you would need a triangular shaped structure whose bottom angles are 450 each. Possibly an Egyptian pyramid?
