How to label an oblique triangle

This video tutorial introduces the concept of dealing with triangles, starting with right triangles and the use of trigonometric functions like sine, cosine, and tangent. It then transitions to oblique triangles, which may not contain a right angle. The tutorial emphasizes the importance of correctly labeling triangles using uppercase letters for angles and lowercase for sides, ensuring consistency throughout. The video aims to equip learners with the skills to determine the remaining lengths and angles of given triangles.
