Trigonometry in triangles explores the relationship between angles and side lengths, crucial in right-angled triangles. It involves trigonometric ratios like sine, cosine, and tangent, leading to identities such as the Law of Sines and the Law of Cosines. These principles are applied in measuring heights and distances, with practical uses in fields like engineering, physics, and geography. Mastery of these concepts is vital for various technical applications.
