Trigonometry on Khan Academy: Big, fancy word, right? Don't be fooled. Looking at the prefix, tri-, you could probably assume that trigonometry ("trig" as it's sometimes called) has something to do with triangles. You would be right! Trig is the study of the properties of triangles. Why is it important? It's used in measuring precise distances, particularly in industries like satellite systems and sciences like astronomy. It's not only space, however. Trig is present in architecture and music, too. Now you may wonder...how is knowing the measurement and properties of triangles relevant to music?? THAT is a great question. Maybe you'll learn the answer from us in these tutorials!

Special thanks to John Green! And to Amber Faasen and the Dallas Zoo herpetarium team!

During the 2017 Project For Awesome livestream, I promised I’d make a tuatara video if we hit our fundraising goal, and I’m a man of my word! Little did I know I’d get to meet a tuatara and learn things about a 200 million year old branch of life that would blow my mind. Get ready to meet the chillest reptile, weird living fossil, and star of Turtles All The Way Down… the tuatara.
