Understanding Tangent Values in Right Triangles through Similar Triangles

This video tutorial explains how to calculate the tangent of an angle in a right triangle using the ratio of the opposite and adjacent sides. It introduces the concept of reference angles and identifies the sides of a triangle. The lesson highlights that tangent values remain constant in similar triangles. The mnemonic SOHCAHTOA is used to differentiate between sine, cosine, and tangent ratios. The tutorial concludes by reinforcing the understanding of tangent values through properties of similar triangles.
