👉 Cotidal is a term used in mathematics to describe an angle that is equal to its complement. Specifically, cotidal angles are defined as follows: - If two angles are cotidal with respect to each other, then their sum is 90 degrees (or zero). - For example, if the first angle is 30 degrees and the second angle is 60 degrees, then their cotidal angle would be 15 degrees. Cotidal angles are important in trigon
