👉 In mathematics, a coterminal angle is an angle that can be defined as the ratio of its position to one of the angles with the same measure. For example, if we look at the angles 60 degrees and -60 degrees, they are both coterminal because they have the same absolute value (180 degrees), but their corresponding angles differ by 360 degrees. In this context, a coterminal angle is defined as an angle whose measure is in
