Trigonometric Ratios in Right Triangles

The video tutorial introduces trigonometry, focusing on right angle triangles. It explains how to label triangle sides and use trigonometric ratios (sine, cosine, tangent) to solve for missing sides and angles. The tutorial includes multiple example problems to demonstrate these concepts and concludes with additional resources for further learning.
