About

Triangles are three sided polygons with a lot of unique properties. From finding the distance between two points, to finding the area of any regular polygon, and even to trigonometry, triangles appear in a lot of places throughout mathematics.

Hello, my name is Colston! I'm a high school student from Northern California, and I love helping others learn. Tutoring is the best way to learn, after all. If you really understand a topic, you can break it down into simple terms and concepts. Outside of academics, I play euphonium in both marching and concert band, which means I have an intermediate level of music theory knowledge. I also enjoy skiing and exploring intro-level coding. I'm always looking to challenge myself.
