Coterminal angles are two angles that have the same terminal side. In other words, when two angles share the same endpoint, they are coterminal. For example, if you have an angle of 30° and another angle of 390°, they are coterminal because they both point in the same direction. This concept may seem simple, but it has far-reaching implications in trigonometry. By understanding coterminal angles, we can simplify complex trigonometric expressions and solve problems more efficiently.
