The distance from a point to the origin is always positive, but the signs of the x and y coordinates may be positive or negative. Even though the word trigonometry is derived from the word triangle, you'll see a lot of circles when you work with trig! This implies that given a negative angle, we can get its respective positive angle. Trigonometry helps us find angles and distances, and is used a lot in science, engineering, video games, and more!
