The video tutorial introduces trigonometry, explaining its Greek origins as the measurement of triangles. It covers the basic components of a triangle, including angles and sides, and emphasizes the focus on right triangles in trigonometry. The tutorial also highlights real-life applications, such as measuring the height of trees and mountains, using trigonometric principles.
