angle is oriented from the ray containing the first point 𝑩𝑩) to the ray containing the third (point (𝑨𝑨). Customarily, angles (often identified with their measures) are denoted by Greek letters such as 𝜶𝜶,𝜷𝜷,𝜸𝜸,𝜽𝜽, etc. An angle formed by rotating a ray counterclockwise (in short, ccw) exactly one complete
