Finding reference angle
WebJan 21, 2024 · A reference angle is a positive, acute angle determined by the x-axis and the terminal side of a given angle. In other words, it’s always found inside our Reference Triangle, close to the origin, in between the x-axis and the terminal side. That’s great, but why should we care? Finding the Function Values of an Angle WebFinding a reference angle in degrees is straightforward if you follow the correct steps. 1. Identify your initial angle. For this example, we’ll use 440° 2. The angle is larger than a …
